Re: [chuck] Serial or USB access?

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. Jerry
