[sdiy] Digital noise generation

[Antti Huovilainen]

Hi again

I partially solved the problem. Using any two tap noise generator sounded 
quite bad, but testing with 24 bit 4 tap generator produced much better 
results. If anyone has insight to why this is so, please tell.

I have uploaded the matlab code and example wavs to
http://www.acoustics.hut.fi/~ajhuovil/noise/

goodnoise.wav = 24 bit 4 tap noise
badnoise.wav = 23 bit 2 tap noise
rand.wav = matlab's internal random number generator. This one still 
sounds slightly smoother than goodnoise.wav.
