Noise is Beautiful There are some classic examples of Spectral Modeling from Xavier Serra's thesis and work thereafter, wherein he sucks out the deterministic (non-noise, sinusoidal) sounds, leaving only the noise. Then he does some cool transformations. I'll try to put up a directory of these to inspire you. You might look into TAPESTREA, 'cause that's a good tool for doing this type of work. Forge Ahead!!
