True, I know it's probably not the common practice and that's why I did it using FFT... ;-) FIR filtering done in complex plane (frequency domain) is much faster than time-domain processing. I don't think it's easy to get 3th octave (31-band) EQ or nice parametric eq to have low latency in any domain. Anyway, there are various other reasons why it's done in complex plane. Now I'm able to run such 8-channel eq at 96 kHz if needed. - Jussi Laako -- PGP key fingerprint: 161D 6FED 6A92 39E2 EB5B 39DD A4DE 63EB C216 1E4B Available at PGP keyservers
