WebThe theory of digital sound Basic signal theory. As you probably know, sound is air which is moving very quickly.The speed of these movements is called "frequency", which is a very important property of sound, especially music.The frequency of a sound is measured in Hz (=Hertz, named after a man called Hertz :-/ who did a lot of research into sound and …
WebAudio means "of sound" or "of the reproduction of sound". Specifically, it refers to the range of frequencies detectable by the human ear — approximately 20Hz to 20kHz. It's not a bad idea to memorise those numbers — 20Hz is the lowest-pitched (bassiest) sound we can hear, 20kHz is the highest pitch we can hear. Webdispel the wide spread misconceptions regarding sampling of audio at a rate of 192KHz. This misconception, propagated by industry salesmen, is built on false premises, contrary to the fundamental theories that made digital communication and processing possible. The notion that more is better may appeal to one's common sense. Presented with ...
