pitch shifters for sound synthesis?

2003-04-30 by kdakan

hi. i was curious if you can use pitch shifter effect to add
harmonics and actually synthesize different instrument sounds from
any signal, like a electric guitar sound. I was thinking of filtering
the overtones of the electric guitar sound to make it more like a
sine wave (which would be more usable for building up a sound from
scratch). Which pitch shifter in the market would be appropiate for
this? (It should be fast, accurate, have clean sounds and have many
added voices).

I don't think a pitch shifter (as distinct from frequency shifter) will
really help. It shifts the present frequencies by corresponding ratios. At
best I can see, even with feedback, that all you would generate would be a
sawtooth wave. Anyone else care to take a stab?

Pitch shifters have no ability to add or remove harmonic content
from audio signals. I would experiment with a lowpass
multimode filter.

Well, I guess if you entered a sine, and shifted it up an octave,
you'd have a second harmonic... You could make a third harmonic,
fourth, etc... Added together in appropriate amounts you could
re-create a sawtooth (32 or 64 harmonics needed really). The phase
behavior would probably be horrible, but in theory it could be done.
The number of pitch shifters would probably be mind boggling, and the
financial outlay would make a snake grow hair.

But in the final analysis: starting out with a guitar sound, you
already have a nice harmonic-laden source. Some judicious wave-shaping
will make this even better. So why the ^%$@$ would you use dynamic
filtering to whittle it down to a sine - only to then painstakingly
and at great cost fold it out into a sawtooth again? And then filter
that again with a multimode filter? Just use the multimode filter
directly...

Be good,

Paul
