Title: Deleting audio tracks
Post by: bobn1944 on December 21, 2018, 12:32:40 PM

Hi all. Does anyone know of a program/app that will remove some tracks from an audio file?
What I am trying to do is remove all tracks except drums and the girl talking on Human League's Human
in order to play along with it on my S950.
I have Audacity which is an audio editing program but it only lists two tracks, LH/RH stereo.
You can I believe remove the vocal track using Audacity, but that is not what I want to do.
Any ideas greatly appreciated.

Merry Christmas & a Happy New Year to all

I don't believe that you can do this.

A song is recorded in a studio using a multi-track recorder, then mixed down to a single L/R stereo pair. It's not possible to go the other way, back to multi tracks.

The 'remove vocal track' function is a kind of fudge that analyses the stereo pair and tries to remove what is most likely to be vocal frequencies present in both L and R at the same time.

With Xtra Stems 2 you can do it but the program is not free. I have it and it’s amanzing but not perfect.

I heard a demo of v1 last summer and it works reasonably well. The extracted audio may have some artifacts and drop-outs, but the artifacts can be hidden when mixed with other audio (e.g., your playing).

Audionamix is the company. They just released v2.

All the best -- pj
