I am looking for a program to extract a single instrument (guitar) for the purpose of learning to play it.
I don't care if it costs $ or not as long as it is native to UBUNTU 9.10 .


I have broken the chains of Microsoft

Are you aware that such a thing exists? Intuitively, I tend to doubt it is practical or even possible.

JamVox is an example of equipment that can do this,
but is "Windows" only, I think.

Well for starters I know tracks can be recorded by instrument independently of each other and layered to produce a final cut ie: drum, guitar and vocals provided the timing is correct so I guessed the process was reversible.
You don't know if you don't ask.

I looked at a youtube demo of that software. The song had only a drummer & guitarist, and it seemed that a band filter was used. This filtered out the drums but not the symbols.

I suppose that fancy filters could be used that filter based on the attack of certain frequencies, but I don't think the software that was suggested did anything fancy due to the poor results I heard.

Yes, it can be reversed if you have access to the pre-mix masters of the recording session, but once it's been mixed down to a stereo track (as in every standard consumer audio format), you can't really go back.

I don't know what sort of tools are out there to parse and model instruments out of stereo tracks, but decent ones are probably out of reach for the average desktop CPU and sound card. Even professional studio hardware/software has a lot of trouble with things like that.

As a linux user, I'd say load it in audacious or audacity and play around with the eq's and various ladspa filters, to see if you can make the guitar pop out of the mix. Sometimes the voice-removal plug-in, which cuts center-panned frequencies, will help make other things more audible, sometimes not so much. You can also slow down the track without changing the pitch, but that will usually introduce some distortion, depending on how far you're trying to stretch things...

As a guitar teacher, I'd say use your ears, possibly in conjunction with the above tweaks, and be persistent!

Good luck.

Pretty sure you won't be able to get jamvox to work under linux with wine.

I use audicity, I tend to use 5 to 30 second clips and use change tempo if the parts are faster.

It is best if you use highest bit rate mp3 to convert and use the higher rates as the quality is better on slowed down parts.

I think I paid about $100 for a line 6 ux2 and it was worth it. I suspect the jamvox is too. Vox has been around a while

Might write their technical support people and ask if they have any plans to port to linux. Looks like a neat tool.

If my wife would make a bit more money I could buy one and try it. Their forums say they have no plans to support linux.

Thanks Jim...best advise yet!

I have tried several programs,too many to list here but the result is the same.
They seem to reduce the volume of a track but not remove it and they all leave audio artifacts so I guess it can't be done.
Thanks for all the help.
