How to generate colored noise?
i'm trying reproduce sound effect, , spectrum analysis of effect shows long vertical bars @ regular intervals. said vertical bars indicate many fequencies being played simultaneously.
at first suspected might able reproduce effect using square wave, triangle wave, or sawtooth wave, knew these had sorts of harmonics in them. however, when tested hypothesis in sound forge geerating said waves , analyzing them, found results weren't @ similar had in sound effect.
so i'm thinking need way generate colored noise, perhaps altering white noise using kind of graphic equalizer , retaining frequencies in specific range.
anyone have suggestions in regards this? i guess next step test method involving graphic equalizer, occured me now.
but if works, still either need way perform operation in arduino, or store sample of length play back. i think rather calculate data in code when program starts.

after research graphic equalization came upon parametric equalization , while investigating sound forge's parametric equalizer noticed band pass filter.
i think looking here code bandpass filter, pass white noise.
