Digital Show and Tell

Anyone who is interested in understanding any of the nuts and bolts of digital audio will appreciate this video. Anyone who wants to have any kind of informed opinion about how digital audio sounds, its merits and limitations, should also watch this video. Anyone who thinks that the staircase pattern visible on representations of digital audio somehow mars the sound of 16 bit audio compared to 24 bit audio should watch this video.

It describes sampling, quantisation, dither and the limited bandwidth inherent in digital audio in an entertaining and extraordinarily clear way, using analogue signals, oscilloscopes and frequency analysers. This is a fine way to spend 23 minutes of your time.
