These instructions describe how to record any audio stream that are piped through to your sound system (e.g., external speakers, headphones) using Audacity. Any KDE recording software should work. For the purposes of this example, the audio (voice, music, or soundtrack) player will be Sonic Visualiser but could be any sound source (e.g., MPlayer, VLC, Firefox Flash video, MIDI device).
