I almost forgot--I'm going to need FIR filters. I see a general rational filter that will work, but I wonder about efficiency. I hope to run 15 256-tap FIRs on a 500 MHz G4 Mac. Of course there are FFT libraries around (FFTW, Apple's DSP library, etc.) but I wonder how hard it is to incorporate into ChucK. I apologize if this is covered in the docs, but I didn't see anything about adding external routines.
This made me thinking. Brutefir seems like a good thing to build on: http://www.ludd.luth.se/~torger/brutefir.html Uses FFTW. However, hacking LADSPA support into Chuck should be a good thing, since there is already bunches of packages available there. Having ALSA/JACK support it shouldn't be such a challenge. Cheers, Magnus
