[Trisquel-users] Antwort: Video audio editing

[Igor . Zobin]

That's where GNU/Linux usually shines: advanced video and audio editing.  
Basically any editor you choose will do the job of separating the audio track  
from the video and putting it back together. If PiTiVi doesn't work for you,  
try Lives and kdenlive. Lives is slightly less intuitive as far I can recall.
