Yup, that's pretty amazing isn't it ?, now you can treat your audio like a midi track, their 'Melodyne' app worked real well so i imagine this would be good too.

Research behind this has been going on pretty aggressively for the last ten years. In the field of Music Information Retrieval, the goal has been polyphonic transcription. "Polyphonic" refers to multiple notes sounding at the same time. These can be chords, as in the example in the video, a choir of singers, or even a band. "Transcription" means that the notes can be identified by the software.

Applications of this idea are very profound. Not only can you correct playing or intonation mistakes, but you can transcribe polyphonic recordings. With tweaking, you could conceivably transcribe every Muddy Waters song, etc.

With this kind of transcription, you could search a database of recordings to look at patterns. I would be interested to see how blues licks appear in the repertoire. Who uses them when, how were they modified, and so on.

Single instrument transcription has been around for quite a while, but polyphonic transcription has been a holy grail, since it is a real world situation.

I have made a modest contribution to this research by making a database of recordings available to researchers, or anyone else, for free. These are recordings of orchestral instruments played note-by-note in an anechoic chamber. These recordings are used as a standard for testing new machine listening algorithms. As researchers moved from single note to polyphonic, they would mix these recordings into polyphonic textures. Since the recordings are extremely dry, the sounds do not smear into each other. This is not a real world situation at all, so this was only a first step in the direction of polyphonic transcription.

Anyway, think about it. With texts, you can search all over the internet for word phrases. Now this would be possible for musical phrases. How cool is that?

So now it is possible to make any kind of music from the one source material. Musicians are a dying breed.

I guess it also means that if your engineer is a talented guy , he could take your fairly average solo , and rephrase it into something magical .
I guess it's also possible that he could give you someone elses sound / tone / voice he he

Right enough, but how long will it take to do that versus the budget ?......... then again looking at whatever Saturday night 'talent' show happens to be on i can see it getting a lot of use. (and abuse).

It would take a lot of musical skill and inspiration to do that. That kind of musicality is as rare as a good guitar solo.
