[Dixielandjazz] Eliminating frequencies

[rorel at aol.com]

 Jim:

All you need is a sample - you select a clarinet solo passage of only a few second's duration, isolate it from the accompanying instruments by notching them out, tell the computer this is a clarinet and it pulls out the clarinet from the track.? This would work much like a noise filter where you select a sample, tell the computer "this is noise, remove it."? Only now the process is reversed, "this is a clarinet, remove everything that is not a clarinet."

I never said it would be easy.

I expect to see the day where you can take those Oliver, Armstrong, Jelly
Roll tracks, and isolate the instruments by frequency -- telling the machine
"this is a clarinet, this is? a trumpet, this is a trombone..".?

Ray, I may be wrong (I quite often am when predicting what will happen in
the future), but when you talk about frequencies, they are just that.  A
machine can't distinguish between one instrument an another.  You can
eliminate a frequency in a flash (a good notch filter will do that for you),
but everyone hitting that frequency at that moment will disappear from the
recording.
