Separating sounds within track

[Badger51]

I have a single track of voice and piano.

Is it possible to isolate the voice and amplify it, without amplifying piano?

There are some things you can try:

Vocal Reduction and Isolation is built-into Audacity. It mostly works by isolating or removing the “center” (whatever is identical in the left & right channels) which generally includes the lead vocals. IMO - it’s just a novelty to play with and you rarely get “professional results”.

I’ve not tried these yet:

New AI Music Separation Plug-in.

There is an open-source AI project called Spleeter. (There is more than one website since it’s open source.)

There may other AI projects that can do it, or that will be able to do this kind of thing “soon”.
