I have a song in two languages and I want to get the instrumental. Is there a way that I can get Audacity to compare the two of them and extract what is similar between them, which in this case would be the instrumental? If that’s not possible is there a way to merely get the beat of the song, so there won’t be any vocals?
There are many ways that Vocal removal can fail, but sometimes it is possible. See here: http://audacityteam.org/wiki/index.php?title=Vocal_Removal
