Re: [Phys-l] De-chording polyphonic music with software.

I forwarded Bob's post (bottom) to my horologist, inter alia,  
friend.  Below is his reply:

"I have been following Celemony Melodyne for several months and have  
downloaded the demos. The new component extraction (Direct Note  
Access) looks good in the demo but is months away from sale. The  
current products are less than perfect in determining pitch of single  
guitar strings. The same thing is true of other audio-to-midi  
software I have."
