Record playing sounds with Audacity

  1. If not already installed, add PulseAudio Volume Control (pavucontrol) to your system. This is usually available in the distribution's repository.
  2. Ensure that PulseAudio is running. In Audacity's Device Toolbar, set the Host to ALSA and the input device to pulse.
    • On systems where PulseAudio is the default sound system the input device may be set to default.
    • The output may be set to pulse or to any available soundcard.

    • The playback level of the application being recorded will also affect the level of the recording. Use the "Playback" tab in PulseAudio Volume Control or the volume control in the application to adjust the output level.
  8. When the input level has been correctly adjusted, press the Record button in Audacity .
