Rooms!App Version: 6.7released 2020-01-08 |
If you experience problems with previewing the content of zip files in the Files app, then please read here.
In Rooms! 5.0, the keeping of user presets has changed. In past versions, they were stored in the user defaults, meaning that they got lost when the app was removed from the device. Now they are saved as files in the app's documents directory and as such can be moved to iCloud and shared with other devices. When you open Rooms! 5.0 or later for the first time, an automatic conversion of the presets takes place.
In Rooms! 6.1, the mechanics of the convolution reverb has changed, see here.
New in version 6.4: Rooms! now allows employing the convolution reverb as an audio unit extension. There is a separate documentation for this AUv3 functionality. Using the convolution reverb in the app itself, via IAA or as an Audiobus app, is free. The AUv3 extension is an in-app purchase.
As a quick start for convolution users (in-app or via AUv3), there is now a separate page that details how to install impulse response files.
What is Rooms! ? ⬆
Rooms! is a free iOS application for recording audio and for adding reverb to audio files and to audio streams (Audiobus 2, Audiobus 3, Inter-App Audio, AUv3). Audio files can be uploaded to the app via iTunes File Sharing or by Document Interaction. With iOS 11 and Rooms 4.14 and later, you can also use the iOS Files app. Uploaded files, and files created by the app, can be shared by iTunes File Sharing, by Document Interaction or by e-mail. Two types of reverb are supported: Algorithmic reverb created by an iOS Audio Unit, where you can control all parameters of the reverb effect unit, and convolution reverb. Rooms! has a built-in audio recorder which allows you to save M4A/AAC or WAV files with various sample rates and bit depths and later add reverb to these files. Using playthrough, you can in realtime add reverb to the sound captured by the microphone or from an external sound source.
Possible applications:
- Record your own voice, add reverb, and e-mail the result to your friends ("Listen, I am in Paris right now, visiting Notre-Dame ..."). Of course you can use Rooms! as a plain but comfortable voice recorder and voice mail system, without applying effects to the recorded files.
- Record the sounds in your apartment or the street, the sounds of your pets and household appliances, and experiment with how they would sound in a hall or cathedral.
- Use the playthrough functionality and earphones to listen to your reverberated world.
- If you are a musician, add reverb to tracks of your music productions.
- If you are a guitarist, use the convolution reverb for cabinet simulations (provided you have suitable impulse response files).
- With the Sounding Presets of Rooms! 5.0, you can use the app as a sample player. Different presets can play different sounds or the same sound with different reverb settings.
- Using the Preset Buttons functionality (in-app purchase "Preset Buttons") of Rooms! 5.0, you can configure 3×3 grids with buttons for comfortably selecting presets, including Sounding Presets for playing sound clips. The buttons can be decorated with labels or with images.
- And of course there are all the use cases that a filter app in the Audiobus ecosystem or an IAA or AUv3 effect offers.
- Last not least you can use Rooms! simply as an easy-to-operate, reliable and versatile audio recorder.
For a perfect experience, earphones / headphones or external speakers are recommended. For the playthrough functionality with microphone input, earphones / headphones are mandatory, otherwise a feedback loop is formed.
With version 4.15 and later, it is possible to control some functions of Rooms! by MIDI commands, see below.. This is an in-app purchase "MIDI Control".
System requirements ⬆
Up to version 5.2, Rooms! runs on all iOS devices (iPhone, iPod touch, iPad) with iOS versions ≥ 5.1.1.
Starting with Rooms! 6.0, due to App Store and Audiobus 3 requirements, the minimum target system of the app is iOS 9.3.5. The embedded AUv3 app extension needs iOS 10.3.3 or later.
Audiobus, IAA and iCloud support are available on iOS versions ≥ 7. Slide Over and side-by-side view support is available on iOS versions ≥ 9 and iPad Air 2 or better.
For using convolution reverb in realtime, at least an iPad 4 or iPhone 5 is recommended. Impulse responses that are too long will lead to reduced sound quality or even to stuttering or missing sound. You can try the suitability of your device with help of the included demo impulse responses.
Localizations ⬆
Rooms! supports the following languages:
- English
- German
Privacy Policy
This is the privacy policy declaration required by Apple: Privacy Policy of Rooms!
Using the app ⬆
Rooms! is built of five main views, each of which can be selected by the tab bar at the bottom of the screen. The icons, by the way, are elements of Jan Kovařík's GLYPHICONS library:
- Use the Recorder view to create audio recordings with your device's internal or a suitable external microphone or another external sound source. The files are saved to the app's documents folder.
- The Files view shows a list of the files in the (local and iCloud Drive) documents folders of the app: audio files, cancelled recordings, and impulse response archives. You can play audio files with or without added reverb. Action menus offer additional functionality like moving files to/from iCloud (if you have enabled iCloud usage for Rooms!). Starting with Rooms! 5.0, there can also be image files in the documents folder, which you can use to decorate the preset buttons.
- The Parameters view lets you select the reverb type (iOS Audio Unit reverb or convolution reverb) and change the parameters of the reverb. This can be done while audio is playing, so the resulting effect can be heard immediately. When you are happy with the outcome, you can create an audio file with reverb, which you can transfer to other apps for further processing. You can also save the reverb parameters in a user preset. For iOS reverb, there are buttons for loading a preset from a list of factory presets or user presets.
- The User Presets view shows a list of the saved presets. You can rename or delete user presets. When you select a user preset, its parameters are immediately taking effect. Starting with Rooms! 5.0, you can design preset buttons in a grid layout. You can assign a label or an image to each preset button. Toggle between the list view and the grid view by repeatedly tapping the User Presets tab bar icon.
- In the Settings view you can configure various parameters. Furthermore, it has an action menu with options to view version information, to show the available in-app purchases, to show the app's description in the App Store and to display the app's support page (the page that you are viewing right now) in Safari.
The views and their usage shall be explained below in more detail.
In all of the main views there is a microphone button in the top left. This button activates the playthrough mode, i.e. audio in (microphone or external sound source) is directly routed to audio out, but with added reverb if you select "iOS AU" or "Convolution" in the Parameters view. While playthrough is active, the microphone gets a red color.
When using microphone input, please activate playthrough only with earphones or headphones, because otherwise you create a feedback loop and get ugly high-pitched noise. We are not liable for damage done to your ears or speakers. When you unplug the headphones while playthrough is active, the playthrough mode will be terminated automatically.
The Recorder view ⬆
This view has a single button, named Start, which serves for starting a recording, and buttons to select the file format, the sample rate, the bit depth and the channel mode for the recording:
The recorder supports the creation of compressed AAC (Advanced Audio Coding) and uncompressed WAV files.
The supported sample rates are 8, 16, 22.05, 44.1, 48 and 96 kHz. However, this does not mean that the audio will be captured in the requested quality, in particular if you are using the device's internal microphone. Furthermore, the capture sample rate will probably be not higher than the current hardware sample rate of the device, which you can see at the bottom of the Settings view. If you select 48 kHz or 96 kHz, but the hardware sample rate is 44.1 kHz, then the audio data of the file will just be upsampled from 44.1 kHz or whatever the microphone or sound source deliver. Whenever the recording sample rate and the current hardware sample rate differ, the app displays a warning at the top of the Recorder view, because this means an additional resampling process that can reduce the quality of the sound data.
The bit depths are 8, 16 and 24 bit for integer and 32 bit for floating point uncompressed WAV files. For AAC, this setting has no meaning.
The channel mode is Mono or Stereo. Again, selecting Stereo does not give a true stereo file if your microphone or sound source delivers a mono signal. You will just get a file with two identical channels. Only if you connect a stereo microphone or stereo sound source, you will get a real stereo file.
AAC offers good sound quality and requires significantly less SSD space than uncompressed WAV. The setting 44100 Hz / 16 bit gives a frequency range and dynamics that comfortably exceed what your ears can perceive and hence is fine for recording music. A lower sample rate means that you loose high frequencies. With a lower bit resolution you can still record the same frequency range, but it gives a lower signal / noise ratio. For voice messages, 8000 Hz / 8 bit / Mono are good enough and result in smaller files. Use WAV format and 44100 or 48000 Hz and 24 or 32 bit for recording sound that you intend to postprocess or use as an impulse response (see later).
You have to set the parameters before you start the recording. As soon as you tap the Start button, the recording begins and the view displays the buttons Pause, Cancel and Finish. Starting with version 5.2, you can, in the Settings view, set the recorder to a single-button mode where there is only one button which alternates between Start and Finish. This is useful for operating the recorder without looking at the screen, in particular when you use it with the audible recorder confirmations which, too, are new in version 5.2 and can be configured in the Settings view.
While the recording is performed, you can observe the number of elapsed seconds, which is also displayed at the icon of the Recorder view. By tapping the bar graph icon, you can activate a two-channel peak meter. The channels are displayed at the left and the right side of the view:
The usage of the buttons Pause, Cancel and Finish is obvious. Only after you press the Finish button, the recording will be saved to the documents directory and can be seen in the Files view. For the recording's name, you can enter a base name and let it be prefixed or suffixed either with the date or with a counter. The file name pattern is displayed at the lower left of the Recorder view and can be changed after tapping at the text. Of course you can later change the name in the Files view, see below.
The behaviour when a recording is finished can be configured in the Settings view. You can advise the app to either stay at the Recorder view or automatically switch to the Files view and select the recording file.
The behaviour when you cancel a recording can be configured as well in the Settings view. You can choose that cancelled recordings will be deleted or be saved. In the latter case, you can see the files in the section Cancelled Recordings of the Files view. You can later decide if you would like to restore or really would like to delete a cancelled recording.
Furthermore, a recording in progress is not neccessarily lost in case of a system crash. At the next start of Rooms!, the app will see the unfinished recording file and ask if you would like to recover it. Note however that this file will be incomplete and structurally broken. You need an external audio file tool to repair it.
To ensure you don't loose any data in case of an incoming phone call, in this situation the recording is being finished and saved.
The Files view ⬆
The Files view is built of up to four sections, each of which shows the files of a certain type and exists only if there are any files of the respective type. The specifics of each of the four sections will be described below.
At the top right of the Files view there is an action button, which opens a selector for the type of operation: Sorting, Copying/Importing, Deleting and iCloud.
When you select Sorting, you will be presented another menu with the entries by date, by length, and by name, furthermore by date, reversed etc. The meaning of these options is obvious. The currently selected sorting method is marked with a hook. This setting affects only the Audio Files section. Cancelled recordings are ordered by date, impulse archive files and image files are ordered by name.
Copying/Importing gives you a menu with two entries:
-
Import from media library: You can import (not
copy-protected) audio files from your media library. After tapping
this menu item, you get a standard iOS media picker view where you can
select one or several audio items. It is a known and annoying 'feature'
of the media picker that there is no deselect and no cancel
functionality.
In recent iOS versions, the user needs to give permission to let an app access the media library. When you try to import audio files for the first time, iOS will ask you to give this permission to Rooms!. In case of refusal, you won't be asked again at subsequent times, but the media picker won't work. You can change this setting anytime in the Settings app of your device, in the section Privacy – Media Library.
-
Copy short files to IR library: This entry is present
only if there are audio files. It lets you copy all 'short' audio files
(you can select the files with a duration of up to 5, 10 or 15 seconds)
to the
User
set of the impulse response library. After the copy process is completed, you are asked if you would like to delete the copied files from the documents directory.
Deleting opens a menu with deletion actions:
- Delete short audio files: An additional option to delete short files (again, files with a duration of up to 5, 10 or 15 seconds). Audio files that are used in Sounding Presets are exempted from deletion.
- Delete all audio files: Deletes all audio files from the documents directory, but only after asking the user for confirmation. Audio files that are used in Sounding Presets are exempted from deletion.
- Delete cancelled recordings: Deletes all cancelled recordings, but only after asking the user for confirmation.
Finally, selecting iCloud gives you the option to move all audio files from the device to iCloud or vice versa.
Now we come to the specifics of the four sections of the Files view.
Audio Files section
This is a list of all audio files in the app's documents directory, whether they were created by the app's audio recorder, uploaded by iTunes File Sharing, imported from the media library, or handed to the app by Document Interaction.
Rooms! supports iCloud to make it easy to share files with your other iOS devices, with your Mac, or with other apps. When you enable iCloud Drive for Rooms! in the device settings, you see an icon to the left of each audio file which indicates if the file is stored locally (iPhone symbol) or in iCloud (cloud symbol). The action menu that you get by long-tapping a file has an entry for moving the file from the device to iCloud or vice versa.
When you select an audio file, you get play controls at the bottom of the view and volume controls either at the left or at the bottom of the view (the location is configurable in the Settings view). Tap the file again to deselect it. When an audio file is selected, the slider shows the playing position and can be moved to jump to a different position. You can also long-tap the time display and enter the number of seconds. During playback, the label in the tab bar shows the elapsed time:
If you have activated reverb in the Parameters view,
then when you select a file in the list, reverb will be added when you
play this file. However, when you select a file whose name has the suffix
"+ Reverb
", the app will deactivate the reverb.
The behaviour is this way because the suffix "+ Reverb
" is
appended by the Copy with reverb function, which shall
be described shortly. However, if you would like to add a second layer of
reverb, you can, after selecting the file, still reactivate the reverb in
the Parameters view.
When you later select a file that does not have this suffix, the app will restore the previous state. I.e. when reverb was / was not active before you selected the file with the suffix, the reverb will / won't be active when you later select a file without the suffix.
Deactivated reverb is indicated by "‐" as the icon of the Parameters view:
You can delete an audio file by swiping its entry to the left. By long-tapping you select the file and get an action menu with a subset of the following options:
- Play: Plays the selected file.
- Play as loop: Plays the selected file in an endless loop. This is useful in particular for short files. It gives you time to experiment with reverb parameters.
- Create Sounding Preset: This option is new in Rooms! 5.0. It creates a preset that plays the selected audio file. You can add a reverb setting to this preset in the User Presets list view.
- Copy – Copy to M4A/ALAC: Copies the selected file to an M4A file with Apple Lossless Audio Coding. The size of this file is typically about 50% smaller than that of a 44.1 kHz / 16 bit WAV file, but no quality is lost. This option is not available if the selected file is an MP3 or M4A file.
- Copy – Copy to M4A/AAC: Copies the selected file to an M4A file with Advanced Audio Coding. The size of this file can be about 90% smaller than that of an uncompressed WAV file. This option is not available if the selected file is an MP3 or M4A file.
- Copy – Copy with reverb, 16 bit: Creates a new 16
bit WAV file by adding reverb to the selected file. The WAV file's name
is built by adding the suffix
+ Reverb
to the name of the selected file. By selecting No reverb in the Parameters view, you can (mis)use this function to convert other file formats to WAV files. - Copy – Copy with reverb, 24 bit: The same, but a 24 bit WAV file is created.
-
Copy – Copy to impulse responses: Copies the
selected file to the
User
set of the impulse response library. This is possible only for files with length up to 60 seconds. - Duplicate: Create a copy of the file. You have to enter a file name.
- Rename: Allows you to change the name of the selected file.
- E-Mail: Lets you send the selected file as an e-mail attachment. Remember that you can convert a WAV file to an M4A file to get a smaller size.
- Open In...: After tapping this option you can select an app, provided there is another app that has registered to handle the selected file type. Usual candidates are other sound processing apps or sharing apps. With iOS 11, you can copy the file to iCloud Drive and then access it with the Files app on iOS, with the Finder on macOS or with any web browser at the icloud.com service.
- Move to iCloud: For moving the file from the local storage to the app's container in iCloud Drive. It is then directly available to instances of the app running on other devices. Starting with Rooms 6.4, the iCloud files are also visible for the Files app and in the iCloud Drive section of the macOS Finder.
- Move to device: For moving the file from the app's iCloud container to the local storage.
If a files is being used for a Sounding Preset, then this is indicated by a button symbol before its name:
You will get a warning when you try to delete a file of this kind. When you rename an audio file, all affected presets are modified automatically.
Cancelled Recordings section
Because it may happen that you cancel a recording by accident, or cancel it by intention but decide later that it was not so bad after all, we thought it would be a good idea to preserve the files in the first instance. Remember, however, that cancelled recording are kept only if the appropriate option in the Settings view is set.
The action menu that you get by long-tapping a cancelled recording has options to play the recording, to restore it to the Audio Files section, to rename it, or to move it from the device to iCloud or vice versa. Swipe to the left to delete a cancelled recording.
Impulse Response Archives section
The Files view does also serve for managing impulse
response archives in the app's documents directory. An impulse response
archive is a zip file with extension zip
or irset
, containing impulse response files. You can use
iTunes File Sharing to transfer impulse response archives. You can also
use the Download zip archive function that you find in
the action menu of the Convolution tab of
the Parameters view. Or you can use Document
Interaction, for example by long-tapping e-mail attachments or tapping a
suitable link in a web page. Again, you can share IR archives with your
other iOS devices via iCloud. For more details about impulse response
file management, see here.
As usual, you can delete a file by swiping its entry to the left, while long-tapping opens a menu to unpack the archive to the impulse response library, as well as the usual rename etc. functions. Even when you have unpacked an impulse response archive, it is a good habit to preserve the archive in the documents directory. This helps keeping the impulse response library tidy. If you don't need an impulse response set, you can delete it from the library and possibly re-install it later by unpacking the archive once again.
Image Files section
This section shows image files that you have uploaded to the app with any of the common methods or (in Rooms! 5.2 and later) taken with the camera or imported from the photo library. The images are intended to be used as button images for the presets grid view that is new in version 5.0 of Rooms! (see below for a description of this feature). For example, images of guitar amplifiers would be appropriate if you use Rooms! for cab simulation.
The Fender Guitar Amplifier image in this screenshot is a Wikimedia Commons preview file, see commons.wikimedia.org.
Image files that are linked to a preset (see User Presets) are handled like audio files that are used in a Sounding Preset, i.e. they are marked with a button image, they can be deleted only after a warning, and renaming leads to an automatic modification of all affected presets.
The Parameters view ⬆
In this view you can select the reverb type:
The available settings are:
- Off: No reverb is added, so there are no parameters. With Save you can create a "no reverb" preset, if you wish so.
- iOS AU: The reverb is created by an iOS Audio Unit. There are sliders to control the parameters of the Audio Unit.
- Convolution: The reverb is created by a convolution reverb engine. You can select the impulse response.
The iOS AU reverb ⬆
This is an algorithmic reverb created by an iOS Audio Unit. There are seven sliders to control the reverb:
You can operate the sliders while a file is playing in the Audio Files view or while playthrough is active, and the change will take effect immediately. If you would like to enter a specific numeric value, you can do this after long-tapping a parameter name. Tapping the Random button gives random values to all parameters. The parameters Dry/Wet and Gain are exempted from the randomisation.
If you discover a parameter combination that you would like to remember, then you can save it as a user preset by tapping the Save button. When there are iOS AU user presets, the view offers the button User Presets to load the parameters of a user preset. There is also a button Factory Presets to load any one of the five factory presets:
The convolution reverb ⬆
If you would like to read some general explanations about convolution reverb, please have a look at About Impulse Responses and Convolution.
This is real convolution reverb, not just a half-hearted mix of early reflections and algorithmic reverb. You are presented a list of available impulse responses. To select an impulse response (IR), simply tap its name. The selected IR is marked by a checkmark. If you tap the selected IR again, it gets deselected.
Impulse responses are organised in impulse response sets. Additionally to the above description of the Impulse Response Archives section of the Files view, see here for an explanation of how to get impulse responses into the library. There are a few demo IRs in the IR set "Demo" which can be created by tapping the corresponding entry of the action menu at the left bottom of the view. These are four short IRs of Fokke van Saane (see below) which allow you to test the suitability of your device to act as a cabinet simulator (short IRs, short audio buffer sizes for low latency), and four longer IRs of simple geometric rooms whose purpose is to let you check your device's capability to create reverb (long impulse responses, longer audio buffer sizes). You can upload and use more interesting IRs.
The IRs of the Demo set are free. You are allowed to use them for any
purpose, without any restrictions. If you would like to use one of these
IRs outside of Rooms!, then copy the IR to the documents directory (there
is a menu entry Copy to Audio Files in the action menu
that you get after long-tapping an IR). In the
Audio Files view, you can export the IR file
by E-Mail or by Open In....
You can also download these files directly from polaron.de
:
Small
Square.wav
,
Large
Triangle.wav
,
Large
Square.wav
,
Very
Large Octogon.wav
.
Technically, an IR set is just a subdirectory of the subdirectory
ImpulseResponses
of the app's Library
directory. The IR set list view shows the names of these subdirectories
and all sound files in the respective subdirectory and its nested
subdirectories.
The "+" icon at the top right of the view is for creating a new, empty IR set. This and the options Copy to other IR set and Move to other IR set in the IR context menu (which you get after long pressing an IR entry) help when you have many impulse responses and would like to organise them in a certain way. The context menu also allows you to rename an IR or copy it to the documents directory (so it can be seen in the Files view). An IR can be deleted by swiping to the left.
Ideally, the impulse response files are located in the top folder of the impulse response set. However, it can happen that you get a zip file which contains impulse responses in some directory hierarchy. Rooms! copes with this case by showing the relative directory path instead of the name of the impulse response. You can use impulse reponses in nested directories as usual. However, you cannot edit directory hierarchies. If you copy or move an impulse response to a another IR set, it will always be placed in the top folder of the other set.
Left to the name of each IR set there is an action button. Its action menu has options to show the description file, the comment file and the license file of the IR set (if these files exist), to rename the IR set, to delete the IR set, and to export it as a zip archive. Note that, even if you see just a flat list of impulse responses, an IR set that was imported from an archive can contain a hierarchy of subdirectories, and non just audio files, but other files as well. Create zip Archive creates an archive of the complete directory tree of an IR set.
Convolution is a computationally rather expensive mathematical operation. The convolution engine of Rooms! works with FFT (Fast Fourier Transform). It uses all processor cores in versions < 6.0 and, thanks to speed optimisations, just two cores in versions 6.0. More optimisations made it feasible to limit the processing to one core, so for version 6.1 we decided to abandon parallel operation in favor of better cooperation with other apps. Rooms! employs vector operations to achieve the highest possible throughput. Offline reverberation (Create copy with reverb in the Files view) is usable on all devices, but to be able to process juicy impulse responses in realtime (i.e. playing a file while adding reverb, using the playthrough function or using Rooms! as an Audiobus filter or IAA effect) you need the fastest available devices.
Dropouts of the sound are a no-no. It is better to accept a downgraded reverb quality than to get stuttering sound or dropouts. If Rooms! is not able to complete the calculation in time, then the convolution operation will be terminated prematurely. Starting with version 6.1, the allowed time can be configure in the Settings view. When a timeout happens, this means a loss of reverb quality, which is indicated by a yellow warning triangle:
In Rooms! versions before 6.0, this warning was displayed above the tab bar and tool bar. Starting with version 6.0, it is shown at the right of the tab bar. Due to the limited space, it is placed on top of the Settings button if the app is running on iPhone. Do not worry – the Settings button can still be used.
The convolution reverb can deal only with audio buffer sizes that are a power of 2. Depending on the settings, on the device model and on connected audio hardware, it may happen that the audio callback is using odd buffer sizes. In this case a warning is displayed which indicates the requested number of frames:
Usually, this situation is only temporary, for example when audio hardware is being attached or detached, or it happens when sample rate conversions are done in an IAA or Audiobus setup. It is advised to keep the values of Preferred HW Sample Rate and Preferred IO Buffer Duration in the Settings view at the selection Sys to reduce the risk of getting odd buffer sizes. If you still happen to get this problem, you can try to switch the sample rate to some other value and then return to the Sys setting. Usually this will remedy the situation.
Rooms! measures the time needed to calculate the convolution. When you select Show convolution time in the Settings view, you get a milliseconds display at the icon of the Parameters view (if convolution reverb is activated):
Version ≤ 6.0: The displayed value is the average time needed for the 'tail' processing that is done concurrently to the audio thread. The 'head' processing that is done inside the audio callback is much faster and negligible compared to the 'tail' processing.
Version ≥ 6.1: No concurrent processing is done anymore. The displayed value is the maximum time needed for a complete run of the convolution reverb function.
Again, there is a Save button in the bottom right of the view, which lets you create a preset from the currently selected IR.
Furthermore there is an action button in the bottom left of the view, which opens an action menu with the following entries:
Here you can select whether the IRs within an IR set are displayed sorted by file date, by file length, or by name. To install the included demo impulse responses set, select Create Demo IR set. This does not need network access, and if you have deleted some or all of the demo files, you can install them again at any time.
You can also download impulse responses from within Rooms!. There are two ways to do this.
One option is to download zip archives. After tapping Download
zip archive, enter or paste an HTTP address of a zip file. The
file name needs to have one of the extensions
zip
or irset
.
The app has no safe way to detect whether an entered address contains
escaped characters or not. Hence an unescaped address is assumed, and the
app cares for doing the transformation when it creates a download URL. If
the downloaded file is suprisingly short and cannot be unpacked, then
maybe you have typed an address with escaped characters and downloaded an
error page.
This is an unsatisfactory state, and typing or copying/pasting HTTP
addresses is inconvenient, anyway. As there are nowadays other options to
download files from the internet into Rooms! (tapping a link in Safari;
using the Files app), we are considering to drop this internal download
functionality altogether.
The other method is file-by-file download of IR sets by tapping Download IR set, using a format which is explained here. We have prepared IR sets with impulse responses of Fokke van Saane and of Voxengo so you can download and install them with a few taps. We would like to point out that we are not selling these impulse responses. They are available for free at http://fokkie.home.xs4all.nl/IR.htm and http://voxengo.com/impulses/, respectively. We only offer you a convenient way to install the IRs so you don't need to import them manually.
Fokke offers only some of his IRs in WAV format. We used Audacity to convert some of the others. For the case you would like to use the converted IRs with software other than Rooms!, download http://polaron.de/Rooms/van Saane.irset to an empty directory on your PC or Mac, replace the suffix "irset" by "zip" and unzip the file. Like Fokke's files, the converted files are freeware.
The impulse responses of Fokke van Saane are recordings captured with a microphone in real rooms, including funny setups like a vacuum cleaner tube or a bathtub. You can create IRs like this yourself, for example with the audio recorder of Rooms! and a good external mic (use Audacity or another sound editor to postprocess the files). The Voxengo IRs on the other hand were designed with Voxengo's Impulse Modeler software. Creating IRs by software has the advantage that you can model any room geometry, real rooms as well as rooms that exist only in your imagination, and you can simulate arbitrary positions of the sound source and of the listener. Besides that, other than microphone-captured IRs, modelled IRs are free of noise. The larger Demo IRs were created with the Voxengo Impulse Modeler, too.
When you select Download IR set in the action menu, you
are asked for an HTTP address. The field is pre-filled with the
address polaron.de/ImpulseResponses/
. This is the place
where we have prepared the above-named IR sets. Before you download a set
you are offered to view the description file, the comment file and the
license file of the set. When you select a Voxengo set, for example, the
license file looks like this:
When you install many IR sets, the IR table can get quite long. The index at the right side helps to speed up the navigation. Just tap the name of an IR set to scroll to its impulse responses:
The button Tweak offer the following parameters to fiddle around with:
- Channel Mode: Stereo means that the left audio channel is convolved with the left IR channel, and the right audio channel is convolved with the right IR channel. Mono Left convolves only the left audio channel with the left IR channel and outputs the result on both channels. Mono Right works accordingly. Mono LR is new in Rooms! 6.7. It calculates, by averaging both channels, a mono signal from a stereo input, then convolves this with the left IR and with the right IR and outputs a stereo signal. The modes Mono L and Mono R obviously need less processing time than the modes Stereo and Mono LR. Please also read About Impulse Responses and Convolution for more details.
- Dry – Wet: 0% = dry signal and 100% = wet signal. This has an immediate effect on the sound, while changing the two following parameters has an effect only when the slider movement has completed.
- x^t Transform: This applies the named transform to the IR values. You can set t in the range [0.5, 2.0]. t = 0.5 corresponds to the square root function and gives an emphasis to small values, hence to the reverb tail. The default t = 1.0 does not change the signal. Larger values dry up the reverb.
- Temporal Reflection: This creates a convex combination of the IR and its reflection in time. 0% = the unchanged IR, 100% = the reflection of the IR.
Reset sets all convolution parameters to their default values, which are Stereo, 100% wet and no manipulation of the impulse response.
Starting with version 6.0, the Tweak button is coloured red when the parameters are different from their default values, which is particularly helpful when you work with a Dry – Wet setting of 0% at some point and then forget about this and later wonder why there is no reverb.
The User Presets views ⬆
This is the area where the most changes happened in Rooms! 5.0 compared to the previous version 4.15. Up to 4.15, the User Presets view was just a list of presets that could be installed by tapping, renamed or deleted. Starting with 5.0, there are now actually two presets views, a list view and a grid view. You can toggle between these two views by tapping at the User Presets toolbar icon.
Furthermore, as the presets are now stored in files, they can be moved to iCloud. Attention: For Sounding Presets, and for presets that refer to images (as decorations of preset buttons in the User Presets grid view), you also need to move the corresponding audio and image files to iCloud if you would like to use these presets on another device.
The User Presets list view
This view is still extremely simple. It is just an alphabetical list of the reverb presets that you have saved by tapping Save in the Parameters view or by selecting Create Sounding Preset for an audio file in the Files view. Long-tap to get an action menu with the following options:
- Set reverb: This copies the current reverb parameters to the selected preset. When you have created a Sounding Preset in the Files view, then this is the way to add reverb to it. When the current reverb setting is "Off", then the reverb will be deactivated before the corresponding Sounding Preset is played.
- Remove reverb: Removes the reverb setting from the selected preset. This makes sense only for a Sounding Preset. A Sounding Preset without a reverb setting does not change the current reverb and is played with whatever the current settings are.
- Set sound: Select a sound file to make the selected preset a Sounding Preset.
- Edit playback parameters: This option for Sounding Presets is new in Rooms! 5.1. It opens a view where you can set the start time, the end time, and the volume of the Sounding Preset. Setting the start time allows to skip leading noise. The values can be set using sliders or, after tapping the label of a parameter, numerically.
- Remove sound: If the selected preset is a Sounding Preset, then this removes the relation to the audio file. This does not delete the audio file, nor does it affect the reverb settings or the MIDI control settings of the preset.
- Set label: With this you can set a label that will be used for preset buttons referring to the selected preset (see User Presets grid view).
- Remove label: If a label was set for the selected preset, then you can remove it with this option.
-
Set image: With this you can set an image that will be
used for preset buttons referring to the selected preset
(see User Presets grid view). Starting with Rooms!
5.2, this option lets you select the following image sources:
- file: This is for selecting an image file, like in earlier versions. (Provided you have uploaded image files to the app.)
- camera: This is for using the camera to take a photo to set it as an image for preset buttons. You need to give permission to the app to access the camera. The image will be scaled to a resolution of 1024×1024 and saved to the documents directory, with the current date and time as file name. You can change the file name in the Files view. It does not matter whether you take the image in portrait or landscape mode, as only the central square of the image will be used.
- photo library and saved photos: These are for importing an existing photo for using it as an image for preset buttons. You need to give permission to the app to access the photo library. Concerning the resolution, the file name and the used section of the photo, see the camera option.
- Remove image: If an image was set for the selectec preset, then you can remove it with this option.
- MIDI Learn: This is for configuring MIDI control for the selected preset, provided you have enabled MIDI in the Settings view.
- MIDI Remove: Removes MIDI control for the selected preset.
- Duplicate, Rename: These are the usual file operations.
- E-Mail: You can send the preset to another user, but don't forget that for a Sounding Preset or a preset with a button image you also need to send the audio file and the image file.
- Open In...: This allows you to handle the preset files with the Files app if you wish to do this for whatever reason.
Furthermore, there are the usual iCloud options, and you can swipe to the left to delete the preset. Simply tap an entry to load the preset. For a Sounding Preset, this starts a playback of the corresponding audio file. If the Sounding Preset includes reverb parameters, then beforehand these reverb parameters are installed, but only if no other Sounding Preset is already playing. While Sounding Presets are playing, the top left of the view shows a stop sign. As you might have expected, you can finish the playback by tapping this button.
Presets whose reverb settings coincide with the currently activ settings are indicated with a checkmark. The detail text of each preset shows information about the reverb parameters (if the preset contains reverb settings), the linkage to an audio file (if the preset is a Sounding Preset), the label and image for preset buttons (if these are set), and the MIDI control configuration of the preset (if MIDI is activated in the Settings view and the preset has MIDI control information:
The User Presets grid view
To use the functionality of this view, you need to perform the in-app purchase "Preset Buttons".
The User Presets grid view can hold any number of pages, where each page is built of a 3×3 grid. The user can place preset buttons at the positions of these grids. Browse through the pages by swiping horizontally. The view title gives some orientation about the current page. For example, the title ○○●○ means that there are four pages, the third page being current. The action menu at the top right of the view offers the possibility to add more pages and to remove the current page.
The following must be understood: In this view you do not create presets, but you create buttons for existing presets. More than one button can be created for the same preset, on the same or on different pages. Removing a button does not delete the preset. However, the button data is stored in the preset. Consequently you cannot create two buttons with different labels or images for one preset. Instead, you need to create two presets, each with its own label or image, and then use one preset for one button and the other for the other button.
If you work with several devices and create a button on device 1 with preset A and a button on device 2 with preset B, both at the same position, and then synchronise preset A and B via iCloud, then you get a situation where two buttons are placed at the same position. It is undefined which button will be displayed in this case, so better avoid to do this.
At the beginning, there are no buttons defined. Grid positions with undefined buttons have a dashed border:
Tapping or long-tapping an empty grid position gives you an action menu for adding a button at this position by selecting a preset. Tapping a button loads its preset, long-tapping a button lets you remove this button.
The look of a button depends on its preset's properties:
- If you have set an image for the preset in the User Presets list view, and if the image file can be loaded, then the button is decorated with this image.
- Otherwise, if you have set a label for the preset in the User Presets list view, then the button is decorated with this label. Use single Emoji characters or symbols to get nice labels. (Except if you are on iOS 5 or iOS 6, as Emojis and symbols do not scale on these iOS versions.)
- Otherwise the button is decorated with the preset name.
Buttons with presets whose reverb parameters match the currently active reverb are displayed with a red border.
For Sounding Presets, the behaviour is as described in the User Presets list view: Reverb parameters get established only when no other Sounding Preset is playing, and while Sounding Presets are playing, there is a stop button in the right top of the view that lets you finish the playback at any time.
Starting with Rooms! 5.1, there is an expansion button in the bottom right of the view. This is for changing to full screen mode which shows only the preset buttons and a contraction button for returning to the normal view. There is no edit functionality in the full screen mode and no pages display at the top, but you can still swipe horizontally to change pages. The full screen mode is not allowed during recording.
The Settings view ⬆
In this view you can set some parameters that control the operation of the app:
- After startup show tells if the app, when started from scratch, will show the Recorder view, the Files view, the Parameters or the User Presets view. This makes sense if you work mainly with one of these views.
- At memory warning controls the behaviour of the app when it is receiving an iOS notification because of a low memory condition. The safe setting is deactivate convolution reverb. This frees up memory and is supposed to keep iOS happy. If you choose show warning instead, then the app shows a warning, but does not release memory. You may have luck, but just as well iOS may terminate the app.
- After finishing a recording is for configuring the behaviour of the app when you tap the Finish button in the Recorder view.
- After cancelling a recording determines whether the files of cancelled recordings will be deleted or kept and displayed in the Cancelled recordings section of the Files view.
- Recorder buttons: is new in Rooms! 5.2 and allows you to select between the puristic recorder GUI single button, which has only one button for starting and finishing a recording, and the multi button mode of earlier versions, which has buttons for starting, finishing, pausing / resuming and cancelling.
- Recorder confirmations: is new in Rooms! 5.2, too, and with the option sound lets you add acoustic confirmation sounds to the recorder buttons. These help operating the recorder without looking at the screen. However, if you do not use headphones, then you will also record the start sound at the beginning of the recording. Because of this, there is the option sound and delayed start. This adds a short delay before the recording starts and is usually sufficient to omit the start sound – unless you have turned on reverb, or if your recording room itself has significant reverb.
- Playback volume controls are is for choosing the location of the volume slider and the volume-off and volume-high buttons, which are shown in the Files view whenever an audio file or a cancelled recording is selected.
- MIDI control: Here you can enable MIDI control if you have performed the corresponding in-app purchase. Apart from the modes Off and On there is a mode + Background op. which has the additional effect that the app is kept active when you send it to the background. Use this option with care because it puts additional strain to the battery. When MIDI is enabled, tap the Configure button for defining the details of the MIDI control functionality, see below.
- Preferred HW Sample Rate (kHz): Here you can set the preferred hardware sample rate. Whether iOS will fulfill your wish depends not only on the capabilities of the hardware but also on the behaviour of other apps that are running. When another app has requested a different sample rate, iOS may deny your request. You can see the actual hardware sample rate at the bottom of the view.
- Preferred IO Buffer Duration (ms): Here you can give iOS a hint about your preferred IO buffer duration. Again, depending on the capabilities of the hardware and the needs of other apps, iOS may or may not respect this preference. You can see the actual IO buffer duration at the bottom of the view.
- Convolution Reverb, used time: Here you can select whether the convolution time in milliseconds should be displayed at the icon of the Parameters view. The time is displayed only if convolution reverb is activated.
- Convolution Reverb, max. time: This option is new in Rooms! 6.1 and allows you to limit the time that is permitted for completing the convolution. It is given in percent of the buffer duration, the default being 80%. Choose a smaller value if you are using Rooms! in an Audiobus setup and notice dropouts of the sound because of a high system load or because another app in the audio chain needs more time. In case of a timeout, the convolution processing will be terminated prematurely, and only a part of the impulse response will be used. This is signalled to the user by the timeout warning flag.
Keep the value Sys for the preferred hardware sample rate and for the preferred IO buffer duration if you do not want to change the system's current settings. It is also better to keep the Sys values if you would like to use the app with Audiobus or Inter-App audio. For example, if you start Rooms! before Audiobus, set the preferred hardware sample rate to a value different from 44.1 kHz, start a file playback or activate playthrough in Rooms! and then start Audiobus, then Audiobus will fail to connect to Rooms!.
For the preferred IO buffer duration use a value that corresponds to 1024 or even 2048 or 4096 frames when latency is not an issue. Use smaller values when you need fast response. This reduces the latency but means higher computational demand. The sound may drop out if your device is not fast enough.
At the bottom of the view you see the current hardware sample rate (in Hertz) and buffer size (in frames and in milliseconds). This sample rate and buffer size, usually 44100 Hz and 1024 frames, is used by iOS when it asks the app for audio data, hence for playing audio files and for the playthrough mode. Some apps, like Audiobus or GarageBand, change this to 512 or even 256 frames. Again, low buffer sizes can lead to stuttering sound, even if you don't actually use Rooms! with Audiobus or with GarageBand or other IAA-capable apps.
At the top of the view there is an action button. The action menu offers the options to display a short info about the app, to view the available in-app purchases, and to open the app support page in Safari. Furthermore there is an option to display the app's log, which collects up to 10 of the latest messages of the MIDI system as well as messages related to in-app purchases. You can close the log display by tapping it. In normal operation, the log display is opened automatically whenever a new entry is added (e.g. when you connect a MIDI device) and closed automatically shortly after.
Starting with Rooms! 5.2, there is also a menu entry Edit Access Rights. This takes you to the iOS settings page where you can edit the permission of the app to access the camera (for taking images for preset buttons), the microphone (for recording and playthrough), the media library (for importing audio files) and the photo library (for importing photos as images for preset buttons).
MIDI control ⬆
When you have purchased MIDI control, you can operate the following functions of the app by MIDI messages:
- Audio recorder functions. You can use note-on or program change messages for this.
- Preset selection, as well via note-on or program change messages.
- Parameters of the iOS reverb. Here you can use MIDI controllers, which usually are sliders or rotary knobs.
Defining MIDI controls for preset selection is done in the User Preset view, as mentioned above. The audio recorder functions and iOS reverb parameters, on the other side, are handled by the MIDI Control view, which you get by tapping the Configure button in the Settings view. The MIDI Control view also serves for selecting the supported MIDI paths:
There are four ways to receive MIDI messages:
-
Wired: This includes the following connection types:
- Via an Apple 30-pin or Lightning to USB adapter (also known as "CCK" for "Camera Connection Kit") connected to a MIDI keyboard or other MIDI device with USB interface.
- Via a CCK to an USB – MIDI 5pin adapter to a MIDI device with a classical 5pin MIDI interface.
- Via an interface like the iRig MIDI or MIDI Mobilizer II (for iOS devices with the old 30-pin dock connector).
- Network: For MIDI over network, which in our case means WLAN. This is also known as RTP-MIDI. You need to configure a MIDI network session, which can be done with the Audio MIDI Setup on macOS. We think that network MIDI is complicated and unreliable and cannot really recommend to use it.
- Virtual: For receiving MIDI messages from other apps running on the same device, via a so-called Virtual MIDI port. This makes sense only in combination with the MIDI control mode + Background op., see Settings view. Virtual MIDI is simple and reliable. When you activate the Virtual option, the app advertises itself via Virtual MIDI with the port name "Rooms". Well-designed sender apps allow the user to select the destination port. For apps that give the user no way to select destinations, starting with version 5.0 Rooms! has the switch Virtual autoconnect. If you activate this switch, then Rooms! will automatically connect to all Virtual MIDI senders.
- Bluetooth: For receiving MIDI over Bluetooth. Only recent enough iOS devices support this. After enabling Bluetooth MIDI, you need to tap Connect. You will then be asked if you would like to scan for other devices or advertise this device. With the latter option, the connection must be initiated by the sending device. The first option is new in Rooms! 5.0 and has the purpose to establish connections to devices that cannot do this on their own (like simple MIDI to Bluetooth adapters, for example).
Below the Supported MIDI paths section there is a section Recorder control and a section iOS reverb parameters. After tapping a Learn button for a recorder control you can operate a key of a MIDI keyboard or another switch that sends MIDI note or program change messages to connect this switch to the respective recorder function. In case of a reverb parameter, you have to operate a MIDI controller. The detail text of each entry shows the current state. Entries for which a MIDI control was defined have a cross button besides the Learn button. This is for deleting the respective control definition.
Audiobus support ⬆
On iOS 7 and later, Rooms! can be used as an Audiobus filter to add reverb to audio streams. Following the Audiobus philosophy, the user does not need to configure anything inside Rooms! to enable this, but uses the Audiobus app in the well-known way to add Rooms! to an Audiobus processing path. When Rooms! is operating as an Audiobus filter, you cannot use its playthrough function – you will get a warning if you try to. All other functionality of Rooms! is available in this mode.
Rooms! supports Audiobus state saving. When you create a new preset in the Audiobus app, or update an existing preset, the parameters of the current reverb configuration are saved in Audiobus as they would be saved in a Rooms! user preset. This also allows you to share the parameters of an iOS AU reverb setting with the Audiobus community. It does currently not include the sharing of impulse response files, though.
Inter-App Audio support ⬆
Rooms! has basic IAA support and can act as an IAA effect. In this mode, the IAA host's icon is displayed at the bottom left of the screen:
Tap this icon to change to the IAA host app.
Starting with version 6.0, the host icon is displayed at the left of the tab bar, which in case of iPhone means it is on top of the Recorder icon. As you are not supposed to use the internal audio recorder of Rooms! during IAA operation, we do not see a problem in this.
AUv3 support ⬆
Starting with version 6.4, Rooms! exposes its convolution engine as an audio unit. You can use this feature on iOS 10.3.3+ after performing the corresponding in-app purchase. The user interface of the audio unit is explained here.
Background operation, access to microphone ⬆
Rooms! does normally deactivate its audio session when the app is sent to the background and in consequence gets suspended by iOS. There are however a number of situations where the audio session is kept active:
- When a recording is in progress in the Recorder view.
- When a playback is in progress in the Files view.
- When playthrough is active.
- When Rooms! is acting as an Audiobus or IAA effect.
- When MIDI is enabled with the mode + Background op..
In any of these cases, Rooms! stays running in the background, which is
signalled by a red status bar. This signal cannot be suppressed; it is a
means of iOS to protect your privacy by pointing to the fact that an app
with the audio session
category AVAudioSessionCategoryPlayAndRecord
is active in
the background, which could potentially be recording the microphone
input. The signal is given even if the app is not actually in recording
state. The only way to get rid of the red status bar would be to change
the category to AVAudioSessionCategoryPlayback
, but
unfortunately an iOS bug prevents this. You can read about this issue
here
and here. Rest
assured that Rooms! does not capture microphone input unless you tap
the Start button in the Recorder view.
On iOS 7 and later, you can use the device's privacy settings to prevent
Rooms! from accessing the microphone (in the Settings app of your device,
go to Privacy – Microphone and
deactivate the switch for Rooms!). In this state neither the audio
recorder nor playthrough functionality can be used – you will get a
warning when you tap Start in
the Recorder view or tap the microphone icon.
Avoid keeping Rooms! active in the background when you don't need this. This consumes processing power that might be missing for other apps, and of course it is a waste of battery energy.
Known deficiencies of the application ⬆
The first mention of a bug does not mean that is new in the respective version of Rooms!. Earlier versions can be affected as well.
Rooms! 1.0 (2013-04-26):
- On iPhone, audio is rendered via the phone speaker instead of the music speaker. Thanks to rafael_ollero for making us aware of this problem. Fixed in version 1.1.
- Sometimes the parameter sliders slip to a wrong position when the device rotates. Rotate again to correct this. Fixed in version 2.0.
- When a file with reverb is created from an audio file that has a sample rate different from 44.1 kHz, then the time slider of the audio files view moves with the wrong speed. This phenomenon can be observed only on iPad. Fixed in version 2.0.
Rooms! 1.1 (2013-05-10):
- If headphones are connected when the app is started, then the sound is still output via the device speaker. To get sound from the headphones you have to unplug and re-plug them. Fixed in version 1.2.
Rooms! 1.2 (2013-05-18):
- No new known problems.
Rooms! 2.0 (2013-05-31):
- No known problems.
Rooms! 2.1 (2013-06-28):
- Saving user presets does not work. In about three months availability of 2.1, no user has complained about this! Are the factory presets good enough for all purposes? Fixed in version 2.2.
Rooms! 2.2 (2013-09-17):
- In the Edit mode of the User Presets view, some operation sequences can lead to a crash. Fixed in version 2.3.
Rooms! 2.3 (2013-09-26):
- No known problems.
Rooms! 3.0 (2014-01-06):
- Convolution reverb: When you select "Create copy with reverb" for a file "A" while a file "B" is playing, then the reverberated file "A + Reverb" contains at the beginning artefacts of the sound of "B" (because there is only one convolution engine, which had still stuff of "B" in its guts). Workaround: Stop the file player before selecting "Create copy with reverb" and wait a moment until the sound has faded out. Turn off playthrough also. Fixed in version 3.1.
Rooms! 3.1 (2014-01-22):
- When long-tapping an iOS AU parameter slider, the numerical input view pops up. This is a rather annoying behaviour. The numerical input ought to appear only when the user long-taps the parameter name. Thanks to Patrick Stiegeler for pointing out this problem. Fixed in version 3.2.
- Some short WAV files with 8kHz/8bit/mono do not work as impulse responses.
Rooms! 3.2 (2014-02-17):
- Irset archives cannot be imported if there are nested subdirectories with identically named files. Fixed in version 3.3.
Rooms! 3.3 (2014-03-06):
- No new known problems.
Rooms! 3.4 (2014-03-28):
- The IAA initialisation does not work ("AudioOutputUnitPublish Failed" at app startup on iOS 7) because of a missing IAA entitlement. Fixed in version 3.41.
Rooms! 3.41 (2014-04-02):
- Under certain conditions, Rooms! fails to initialise the audio graph at startup. It seems this happens when another app is running or was running that sets the hardware sample rate to a value different from 44100 Hz. On iOS 5/6 terminate the other app and Rooms! and, after waiting a few seconds, start Rooms! again. Fixed in version 3.50.
Rooms! 3.50 (2014-08-20):
- With convolution reverb, the new preferred buffer size setting of 4096 frames does not work with hardware sample rates of 22050 Hz (corresponding to a buffer duration of 185.8 ms) and less because in these cases iOS switches to buffer sizes that are not a power of 2, and the convolution engine cannot cope with this. The same is true for a preferred buffer size of 2048 frames and a hardware sample rate of 8000 Hz.
Rooms! 4.0 (2014-08-28):
- Handing over audio files to Rooms! via Open In... does on iOS 8 not work with files shorter than 15 seconds. The action selector which lets the user decide between "Audio File" and "Impulse Response" does not appear. Fixed in version 4.1.
- Rooms! 4.0 uses symbolic links for files of the Demo IR set. iOS 8 is changing directory names whenever you install a new version of an app, which breaks the symbolic links. Workaround: You have to delete and reinstall the Demo IR set. Fixed in version 4.1, which creates copies of the files instead of symbolic links.
Rooms! 4.1 (2014-09-27):
- No new known problems.
Rooms! 4.2 (2014-11-25):
-
Under certain cirumstances (other app changing the hardware sample rate
while Rooms! is in suspended state), the playback speed of audio files
is wrong. Workaround: Go to the Settings view, select
a different sample rate and return to the previous value.
Fixed in version 4.3. -
It is not possible to download zipped IR archives which are offered by
a web server via a URL
like
http://.../download.php?...
. Fixed in version 4.3.
Rooms! 4.3 (2015-02-20):
- The playback speed problem is still there. Workaround: See above. Fixed in version 4.4.
- A wrong audio file duration is displayed after a file was imported from the media library. Fixed in version 4.4.
Rooms! 4.4 (2015-02-27):
Rooms! 4.5 (2015-03-23):
Rooms! 4.6 (2015-07-30):
- No new known problems.
Rooms! 4.7 (2015-09-12):
- Sorting audio files does not work. Fixed in version 4.8.
Rooms! 4.8 (2015-10-14):
Rooms! 4.9 (2016-03-14):
- When you delete an audio file while it is playing and put the app to the background, then an error message appears when the app if fetched to the foreground again. This problem was there in (probably) all earlier versions as well. Fixed in version 4.10.
Rooms! 4.10 (2016-04-18):
- Sorting by date or length in the Files view is flawed. The list does not update correctly for example when you add a file, only when you tap the sort button once again. Furthermore, the rename function is messed up when sorting by date or length is active. Thanks to Morris Rolland for making us aware of this bug. Fixed in version 4.11.
Rooms! 4.11 (2016-12-12):
- On iPhone/iPod touch, the playthrough buttons do not always show the correct status. This happens when you leave one of the main views to access a subview, then switch to another main view and tap the playthrough button in this other main view. For example, go to the Recorder view, open the file name configuration view by tapping the text "File name:", then switch to another main view by tapping an icon in the tab bar, and in this other main view tap the playthrough button. When you return to the the Recorder view, its playthrough button will not have adapted its color. Fixed in version 4.12.
- Just an inconvenience: Cancelled recordings can be selected only by long-tapping. Fixed in version 4.12.
- Another inconvenience: When the user tries to import files from the media library, but permission to access the media library was denied previously, then the app ought to inform the user about this. Instead, the media picker appears and then disappears for no apparent reason. Fixed in version 4.12.
- And yet another one: The table contents in the Files view flickers during iCloud uploads and downloads. Fixed in version 4.12.
- When an audio files plays and the app is sent to the background, then the file stops playing when the app returns to the foreground. Fixed in version 4.12.
Rooms! 4.12 (2017-01-08):
- For fresh installations, at least on iOS 10.3, the user cannot give permission to the app for accessing the Media Library. Fixed in version 4.13.
Rooms! 4.13 (2017-05-16),
Rooms! 4.14 (2017-09-25),
Rooms! 4.15 (2018-01-23):
- No known issues.
Rooms! 5.0 (2019-02-13):
- No known issues.
Rooms! 5.1 (2019-03-14):
- The Bluetooth MIDI Connect button does not work on iPad. Fixed in version 5.2.
- Presets Grid View: When there are no preset buttons defined, then, after tapping the expansion button, the full screen view is missing the contraction button. Workaround: Terminate and restart the app to leave the full screen mode. Fixed in version 5.2.
Rooms! 5.2 (2019-03-27):
- When a Sounding Preset is playing and the user starts another Sounding Preset, which includes a reverb setting, then this reverb setting will be installed. This is not the intended behaviour – the reverb ought not to change in this case. Fixed in version 6.0.
- At startup, the icon of the Parameters tab bar entry does not reflect the current reverb state. Even if reverb is off, it shows the parameter sliders icon. Fixed in version 6.0.
- On iOS 11/12: When the device rotates from landscape to portrait, the play controls in the Files view disappear. Workaround: Return to landscape mode. Fixed in version 6.0.
- On iOS 6, iPhone / iPod touch: In portrait mode, long lines of detail text in the Presets List View wrap around, and later lines are possibly not visible. Workaround: Change to landscape mode.
- On iPhone / iPod touch: When the user tries to open the In-App Purchases view while the In-App Purchases view (or the About The App view) is already open, the app would crash. Fixed in version 6.0.
- An additional, superfluous directory level is created when the app extracts a zip or irset archive to the impulse responses library. Consequently, the description, comment and license files cannot be viewed. Fixed in version 6.0.
- Copying files to Rooms! via the Files app with "Share" – "Open in Rooms!" does not work. Workaround: Use the steps "Move" – "On My iPad" – "[app name]" and then select "Copy" in the right top. Fixed in version 6.0.
End of support for iOS 5 (iPad 1, iPod touch 3g) because of App Store requirements.
End of support for iOS 6 (iPhone 3GS, iPod touch 4g) because of App Store requirements.
End of support for iOS 7 (iPhone 4) because of Audiobus 3 requirements.
End of support for iOS 8 as there are no devices that can run iOS 8 and cannot run iOS 9.
Minimum supported iOS version is now iOS 9.3.5.
We cannot anymore fix bugs on earlier iOS versions and hence these will
stay.
Rooms! 6.0 (2019-06-08):
- The sound volume of other apps drops then you start Rooms! ("ducking"). This change in behaviour was not intended. Fixed in version 6.4.
Rooms! 6.1 (2019-07-02):
- Tapping a file in Safari and using "Open In..." to open the file in Rooms! does not work. Workaround: Use "Save to Files" and save the file directly into the documents folder of Rooms!. Fixed in version 6.2.
Rooms! 6.2 (2019-07-09):
- Restoring all in-app purchases gives an "Internal Error" for the Convolution Reverb IAP, as the app does not anymore 'know' this IAP. Simply ignore this message. Fixed in version 6.4.
- Not a bug in Rooms!, but in iOS 12.4 the iOS Files app behaves strangely: When a zip file is tapped, it opens Rooms! instead of showing a content preview. There seems to be no way to get a preview, so this is really annoying. Preliminary fix in version 6.3. Fixed in version 6.4 (hopefully).
Rooms! 6.3 (2019-08-05):
- The IAP error message is still there. Fixed in version 6.4.
Rooms! 6.4 (2019-08-26):
- The "View in App Store" option of the action menu in the Settings view does not work. Fixed in version 6.5.
Rooms! 6.5 (2019-09-04),
Rooms! 6.6 (2019-09-19),
Rooms! 6.7 (2020-01-08)
- No known issues.
