This amazing program allows you to record your favourite music and audio to a file. It can record audio from your system's soundcard, microphones, browsers, webcams & more. Put simply; if it plays out of your loudspeakers you can record it.

It has an advanced timer that can:
* Start, stop or pause recording at a given clock time.
* Start, stop or pause after a time period.
* Stop when the recorded file size exceeds a limit.
* Start recording on voice or sound (user can set the audio threshold).
* Stop or pause recording on "silence" (user can set the audio threshold and delay).

The recording can be atomatically controlled by MPRIS2-compatible media players.
