I could then use Cool edit to generate noise, find the segment I want and break down the partials, and translate them into Csound. I used to have a program that broke the waveform down, but don't know where to download anything like this. I guess I could load samples. > > Any thoughts? Thanks. What do you mean with "periodic"? If you want to generate a noise sound that repeats itself with a fixed period, you could use a delay line to record the first period of noise (generated with an opcode of your choice) and then just read it from the delay lines for the other periods. I used this to write a "scratched vinyl" instrument with short noise bursts and pops that repeated itself with a period of 1/45 minutes. --ll _______________________________________________ csoundtekno mailing list [email protected] Subscribe, unsubscribe, change mailing list options: http://plot.bek.no/mailman/listinfo/csoundtekno
