P.S. Some time back Klaas did explain where the 44.1kHz frequency came from, I recall it was related to video. But I've done a search here and nothing thus far has emerged.
Wikipedia wrote:It also specifies the form of digital audio encoding: 2-channel signed 16-bit Linear PCM sampled at 44,100 Hz. This sample rate is adapted from that attained when recording digital audio on a PAL (or NTSC) videotape with a PCM adaptor, an earlier way of storing digital audio.[6]
An audio CD can represent frequencies up to 22.05 kHz, the Nyquist frequency of the 44.1 kHz sample rate.
