I went to make up some samples and realized im only generating the
noise in the range of [0,1] even though the rest of the audio is
i fixed it and things sound lots better now.
I also played around with forcing the noise to either -1 or 1
(whichever it was closer to), and changing the "sample rate" of the
Lots of cool sounds!
when the noise sample rate is down in the 128/256 rate it sounds like
wayyy old school sound effects (like from before the Apple II days)
As always, thanks for the wealth of info, this list is awesome (:
