- stereo / mono channel selection

- left/right balance +/- 10 dB
- keep screen ON - option so that device does not enter sleep mode

You have to see the magic of automatic sound level / gain control (AGC), especially if you use to record meetings / lectures. It works as follows: it amplifies the quiet sounds to capture all, but then if a loud sound happens, it gets reduced volume to not blow your ears.

App. intended for personal and commercial use.

Recordings are now stored in the app's "recordings" folder. Old recordings are still in the old folders. They can be imported to the app's "recordings" folder using the "+ import files" button in app settings.
