Re: Elapsed time

If you are making audio CDs, export from Audacity as WAV not as MP3.

Are they really numbered 1 to 11? You can run into trouble with some non-alphanumeric characters as described here: http://manual.audacityteam.org/o/man/sp ... racks.html

Re: A Study in Pink

Or are there some coeffs updated during execution? The coefficients change depending on the sample rate. By calculating them at run time the filter frequency can be kept the same. I feel a slight headache coming up when I am looking at your code... At least I didn't write it object-oriented :grin:

I think I'm getting the hang of this biquad stuff now :grin: So here is a really inefficient (slow) way to generate bandwidth limited brown noise: (setf sarray (make-array 44100)) (setq hz 20 q 0.707) (setq w (* 2.0 Pi (/ hz *sound-srate*)) cw (cos w) sw (sin w) alpha (* sw (sinh (/ 0.5 q))) a0 (+ 1...
