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 7.11

The recording time (number of elapsed seconds) can now be shown in the app badge. This can be enabled in the app's settings and needs Notification permissions.

When running the first time after a fresh install, the app now offers to reinstall previously purchased IAP items.

Accessible and usable

This is accessible and usable. Easy to use, and easy to operate. Reverb sounds awesome, and can be turned on or off, if you wish. The only thing I wish you could do is to monitor in realtime while recording, or before you record, maybe that can be added in next update. Overall, amazing app!!

Developer Response ,

Thanks for the compliments. For monitoring, you can turn on playthrough before or during recording. Would it make sense to add an option for automatically turning on playthrough when the recording starts? (provided that headphones are in use)

Absolutely superb recorder. I’ve been using it for a while and it’s the best app out there hands down. So many thoughtful features really help with productivity. Thank you!

One suggestion I’d love to see is an option to auto-play selected audio track (instead of having to press the play button.)

Developer Response ,

Thanks for the suggestion. I will consider this for version 7.9.
