## What is Thafknar?

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).

- 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.

### 4/5 — Great app but…

*2026-04-05, version 8.7*

Great app but the speed decreases on its own making the sound very funny. That bug needs to be fixed

### 5/5 — Amazing!

*2025-05-28, version 8.6*

This convolution reverb is superb! You guys should make a Neural Amp Modeler, it would be a game changer.

### 5/5 — Extremely good!

*2025-02-04, version 8.6*

The app is extremely good, so I gave it a five review. It works very well. Maybe there should be an update to make it even better. New options for the voiceover rotor. with all the parameters and options except for starting and stopping record, as that’s done with a magic tap. Is associated. This means that you can do almost every control from any tab rather than the tab control, or to make it quicker

### 4/5 — Crashing

*2023-10-20, version 8.5*

I’ve heard this app and it sounds great, but when I open it in GarageBand, it says to go in the app to hit in app purchase. Whenever I do that, the app crashes and I can’t use it on GarageBand. Is there a solution?

### 5/5 — Awesome app

*2023-04-27, version 8.2*

Solid performance. Lots of useful convolution parameters. I’m using this daily as part of my main rig, as an IR loader for guitar.  Developer was super responsive.

### 5/5 — Dependable high quality reverb.

*2023-04-19, version 8.2*

This is one of the first reverbs I bought on the App Store & one I constantly return to. The developer consistently updates and improves it. Highly recommended!

### 5/5 — Functional audio recorder with effects

*2023-01-08, version 8.0*

This is my go to recorder for capturing ideas my iPhone.   As far as I can tell it is peerless. I would really love the ability to listen to the files over Bluetooth and I would also really appreciate if there was a way to organize files. Otherwise an outstanding app!

### 5/5 — Very much needed plugin, accessible, usable and versatile

*2022-09-18, version 7.11*

I love IR reverbs, so was overjoyed to find this one! Thank you for creating it!

### 5/5 — Thafknar, eine gelungene praktische App

*2022-08-05, version 7.11*

Vielen Dank Herr Sigg, 
für dieses schöne Programm, mit dem ich auf kleinstem Raum (Smartphone) Audioaufnahmen in guter Qualität machen kann.

### 5/5 — Awesome

*2021-08-03, version 7.8*

Great app, would love to see it get a little makeover

## Version history (last 5 releases)

### 8.9 — 2026-08-17

As the App Store will soon stop accepting builds for iOS versions before iOS 15, we have decided to make Thafknar's full functionality free for iOS 12,13,14 (i.e. you don't anymore need the in-app purchases for these iOS versions). Even on older devices, Thafknar might well serve as a MIDI expander or, with the Preset Buttons, as a self-contained drum machine, for example.

### 8.8 — 2026-08-03

Apparently, the bugfix for the convolution reverb (concerning delayed late reflections) that was intended to be included in the previous update of the app did not make it into the source code of that version. It is included now.

### 8.7 — 2026-03-24

- Audiobus updated to version 3.0.15.1.
- Bugfix convolution reverb: Non-immediate reflections (starting from the second segment of the impulse response) were delayed by one buffer width.
- Bugfix AUv3: On recent iOS versions the audio unit view controller opened with a "No impulse response sets" alert even if there were IR sets.

### 8.6 — 2023-11-10

Bugfix: The Quad convolution mode was broken.

### 8.5 — 2023-08-10

Changes in the Audio Files view of the Thafknar app:

- Long-tap a file and select "Play all from here" to play the selected file and all subsequent files.

- The name filter is now case-insensitive.

- Smoother movement of the current time slider.
