[CAUT] Development in audio recording technology

[Don Mannino]

I was interested in this thread, so I watched the software developer's
demo movie and read much of their information on this software.  I
suspect that the ability to pick out individual notes might not be 100%
reliable.  A voice in the choir certainly wouldn't work, but even
picking out piano notes within a chord might be a problem at times.
 
All of the samples shown use Guitar and/or an individual voice with
other instruments.  With guitars, the individual strings are very often
plucked separately from the others, making it easier for the software to
identify them.  A chord on the piano, especially with the damper pedal
in use, might be a bit difficult for the software - it will have a hard
time telling the difference between chord notes and individual partials.
The designers do not want to separate partials from each other, as when
a particular note is modified, they need the entire note spectrum to
change, not just one partial at a time.  So the software is relying on
the ability to identify the attack of the note, which is why I think a
chord on the piano could be a problem.
 
I was thinking that it would be fun to take a piano recording and modify
the temperament throughout the recording!  It would then be possible to
listen to the exact same performance, exact same piano, but with
different temperaments.
 
I can see how recording engineers would love this software.  It is a
professional tool, and the price is at the professional level.

	What about fixing the _one_  single soprano who sings flat, as
opposed to the whole section? That may take the next generation of this
technology. In the meantime, here in Illinois, we're still left with the
inelegant solution of having to shoot the offending lady.
