Possibly on topic: Some people like to apply insane compression with a lazy attack/release to their bass drums. Then they amplitude modulate the rest of the mix with that. They call it house music. On Fri, Mar 28, 2014 at 5:13 PM, Sampo Syreeni de...@iki.fi wrote: On 2014-03-28, Charles Z

Yeah this is sometimes called bandpass sampling or under sampling ( http://en.wikipedia.org/wiki/Undersampling) and is commonplace in the context of like RF communications and such. But it can also come up in audio applications, for example critically sampled filter banks. I.e. say you split a
