We want Pink noise! A link previously mentioned in this thread offered what they said was "pink noise", along with "white noise" and "brown/red noise" IIRC. I do get a little into a mood to test the "pink noise" to see if it is "truly pink" as opposed to something towards "purple noise"... I hope only as a result of some midrange frequency response dip in my computer loudspeakers ("they are fairly-el-cheapo" that *may* accentuate "lower treble" and "bass end of midrange"). -- - Don Klipstein (don(a)misty.com)

I needed to generate some white, pink, and other cokored/filtered noises for audio testing. I used the Audacity free software program. You can generate colored noise and filter it, then save either the project or the waveform (various formats) for replay. |
