Does anyone know of a simple way to generate Brown noise in Csound?

The "Antispam" nonsense again! I have presumably triggered it in my reply to Casey. Does this have anything to do with www.nabble.com? Hopefully what stopped it before will work again... Richard Dobson |

thanks richard!
actually i was playing with that and noticed that you get zero sound if the value is 1. why do you think that is? Casey View this message in context: Re: brown noise Sent from the Csound - General forum at Nabble.com. |

Sorry, didn't look at the formula in the docs closely enough: use something like 0.999. Lower values may well be OK too - but always good to check with an FFT that can display on log scales, such as CoolEdit/Audition or Audacity. Richard Dobson |

Thanks for the help, you solved the problem. I think a value of about .995 will suite my purposes. It is practically indistuingishable from the brown noise generator in Wavelab 5, which sounds quite good.
