Archive of the former Yahoo!Groups mailing list: MOTM

I agree with the idea of using a non-harmonically related spacing,
although unless you individually tuned the filters to be exactly on
frequency the chances are that the tolerances of the parts would
take care of it. I also was thinking about costs. The key
component in the modular vocoder idea is the VCA. These certainly
wouldn't have to be up to the MOTM standard, but they should still
be of reasonably good quality. I think the envelope follwers could
be done inexpensively since the frequency range they cover would be
narrow.
I also like the modular vocoder idea, but I'm trying to put
additional functions into this module. I'm really interested in
trying to break sounds apart and then reconstitute them. I was
thinking of looking at the area of vocal formants for the strongest
concentration of filters, but also looking at the resonances in
stringed and wind instruments to try to determine the most optimal
filter frequencies. Making the Q variable somewhere along the line
for stronger resonances is also a possibility.
Of course the larger the number of filters the greater the
possibility of noise. I have some really good Ashley EQs in my
studio. Maybe I'll take one of those apart and look at the
filters. They are really outstanding.
What would be really cool is if I could somehow do a Fourier
transform in analog circuitry, extract the spectrum of a sound in
real-time, then reconstitute it with the spectrum modified or
applied to another signal. Maybe a pitch follower and a series of
VCBPFs would work. Hmmm. :/
