Good luck with that! The trouble is that this is a general problem of
filtering of non-stationary signals from each other whose spectra
overlap.
It ain't easy but I expect in some cases you can get lucky.

1. Convert voice + music into text and midi.
2. Then text to speech and midi to music.

IIRC Compandent offered reasonably working software for cleaning speech
from the background. However it worked well only if the initial SNR was
sufficiently high to begin with.

Just wondering Hardy, can it be done by simple high/low pass filtering
into two channels? Hip hop may be difficult, but something like country can
be separated?

Sorry I meant Blind Source Separation.

Phew - if there was I would be the first to sing its virtues! I assume
you mean something like a CD recording of a singer and you wish to
separate the music from the singer?
There a a few approaches (I dount anything works anything near
perfectly). Blins source separation or so-called unsupervised adaptive
filtering. The method to Google is Independent component Analysis.
(ICA). If you get lucky you might even try ordinary adaptive filtering
using the 2 channels from the stereo recording. try subtracting the
channels! I have no idea if there is open-source code on this. To
understand it it is best to write your own. I would doubt if you could
at this time have success but you never know, there just might be an
ICA or adaptive filtering method out there that nearly does the job.

Hi,
Is there any opensource software that
could separate the music and voice
into two separate files ?
Required for one of the experiments.
Thx in advans,
