Default Guitar track sampling/replicator?

Is there a software plug-in or hardware works similar to the "Drumagog" that listen to the guitar sound on a stereo mix(CD) and than home in onto that sound for the entire song to create a seperate guitar-track file? Then from this file it would offer different guitar samplings for user to select.

that would be pretty cool. But I imagine it would be a pretty significant engineering challenge. I think Drumagog works with individual drum tracks within a DAW mix. It would be very difficult, I imagine, to have an algorithm that could recognize the sound of intstrument within the context of a stereo mix of many instruments and extract it. My understanding is that even those boxes that "remove vocals" from CD mixes don't work so well in reality. (I've never tried one but just sayin' what I've heard.)

Welcome to the forum Ronnie.

Since I don't know how experienced you are with sample replacement let me know if you have any questions.

If I understand you correctly you are asking if you can take a finished song and replace the acoustic guitar sound. My short answer to that question would be, probably not.

Does drumagog actually do that though? I thought it could only do that to drum tracks before they are mixed down with the rest of the instruments. If it does do that I could see it being a pretty inaccurate effect seeing as how it would have to deal with any percussive elements of any other instruments (like the pick attack of a loud guitar).

But back to your question, replacing an tonal instument that can play multiple notes is something that DSP processors have not yet tackled completely. There are ways to get semi-accurate results, but not from a fully mixed song. You would need access to the multi-track project and be able to treat the guitar by itself.

First you would need a polyphonic Audio to MIDI converter. We actually had a discussion about a product that claims to do this a few weeks back.

Assuming the product can do all it says it can you would then need to feed that MIDI into a synth or sampler. I would reccomend a software sampler that either has acoustic samples or that you an add too.

I wouldn't imagine anything being able to do that at the moment. If you think of a "guitar's sound" that can vary greatly in tone and pitch. Effects pedals, different capturing techniques, even the different sound eminating from different type of acoustic guitar wood types could affect what might be construed to be a "guitar sound" or not a guitar.

like, since they can emulate different guitars in Variax guitars, maybe the computer technology for this concept isnt too far off... the way technology is eevr expanding minute by minute, i wouldnt doubt it if something came out soon, or else, eventually in the near future...
