[LAU] Formant filters?

[Julien Claassen]

Hello Aaron!
   Look at csounds.com and the udo section. There is a udo called vowel, which 
looks exactly like what youwant. Or you can try Fofilter which is still based 
on grains, but you can feed it an audio signal from which the grains are 
taken. At least, that is, how I understood it.
   In any case: You will need resonating filters. So I think the buterworth 
filters are out.
   Warmly yours
            Julien
