Thafknar is an audio recorder and player and a tool for adding reverb to files and to audio streams (Audiobus, IAA, AUv3; the latter being an in-app purchase).

Upload audio files by iTunes File Sharing or by Document Interaction, or create recordings with the app's built-in audio recorder. Play or save the files with added reverb. Use play through mode for realtime reverberation. The reverb can be created by an iOS Audio Unit or by the app's convolution reverb engine (iPad 4 or better is recommended for realtime usage).

In-app purchases: 

- MIDI Control for controlling some functions of the app by MIDI messages.

- Preset Buttons for selecting presets by tapping buttons which can be decorated with text or images. This can be used to build a custom-designed sample player.

- Convolution Audio Unit for using the convolution reverb engine as an AUv3 app extension.

What’s New

Version 7.2

- Updates the iCloud Drive container name of the app.
- Bugfix: Delayed recording did not work when the app was in the background.
- New: As an alternative to specifying a delay, you can now set a start date for the recording.

Question about file export

I am not sure how to export the audio files from the app... appreciate developers feedback.

AUv3 Convolution is here!

Congrats to the dev on releasing this much needed functionality. Now we have an AUv3 IR loader - bringing convolution reverb and amp sim IRs into the future with AUv3, allowing for more flexible setups and guarding against the deprecation of IAA. Thanks a lot!

Thanks to Markus for his continued support of older hardware. I'm still getting lots of use from my old iPad. Much appreciated,
