Pulse Code Modulation: Difference between revisions

Revision as of 16:03, 4 July 2005

Pulse Code Modulation (PCM) is a method of recording sound as digital data. The amplitude of the audio signal is sampled at a regular sampling rate, and quantized with a fixed bit depth.

This technology was created by Alec Reeves in 1937.
