Using the app
Thafknar 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, impulse response archives and images for decorating preset buttons. 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 Thafknar).
- 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. After doing the in-app purchase "Preset Buttons", 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 in Safari.
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.
