Pulse Code Modulation
<data> (PCM) A method by which an audio signal is represented
as digital data.
Virtually all digital audio systems use PCM, including, {CD},
{DAT}, F1 format, 1630 format, DASH, DCC, and MD. Many people
get confused because "PCM" is also slang for Sony's F1 format
which stores PCM digital audio on videotape.
