Hi folks,
I'm an enthusiast, as you probably know by now, and I have a question. I was reading through the manual for sound forge the other night, and I discovered lots of references to the Nyquist frequency. Does anyone here know what that is, and does it have anything to do with audacity's menu choice Nyquist prompt? any explanation or input would be great.

Thanks,
Chromebuster

Hi, the Nyquist frequency is half the sample rate of a digitally encoded signal. That's the highest audio frequency that the sampling can describe unambiguously - the common example is the CD 44.1 KHz rate, for which the Nyquist frequency is 22.05 KHz.

The Nyquist prompt in Audacity accesses a programming language to control effects processing.

Coolio. I'll definitely be watching out for that now. My last couple of recordings were botched, and I don't know if that has to do with that particular thing or not, but it very well could. And by the way, is Audacity a good editor to have alongside Sound Forge?
