[sdiy] convolution

[dustin sedlacek]

i have asked this before ...but i dont know if it made it to the list ... 
EMU samplers have a effect that they call "transform multiply" ...taken from 
the E4xt Manual "Transform Multiplication: this function merges two sounds 
together in a unique way which can create many strange and beautiful sonic 
textures. Frequencies common to the original sounds are accentuated while 
uncommon frequencies are discarded" 

it is my understanding that this is called "convolution" and it seems to me 
that this can be done in the analog realm also. but i am not sure how 
exactly.
thoughts? ideas ? somehow this makes me think of balanced modulation and 
using multiple balanced modulators to "narrow down" the frequency ranges of 
the input signals ..
