Audacity Forum

What sort of Mac do you have?
Which version of Mac OS X?
Where did you download Audacity from? (the official download is here: http://audacityteam.org/download/)

If you play the music on a software player that support VST plug-ins, then there are muli-band compressors available as VST plug-ins.

Yes.

So do you don't there are primary frequencies of sound that make white noise? I presume your questions means, "if you mix primary coloured lights you can get white light, so can you mix "primary coloured sounds" to get "white noise"?" It doesn't quite work like that. T...

I've gotten an error message saying "Nyquest did not return audio". Try running it again but press the "debug" button instead of the OK button. After the plug-in has completed there will be another window open - this is the "debug window" that may contain information a...
