PCM

The format that describes sound as a series of numbers is often called a raw audio file; the term is PCM (Pulse-code modulation). Examples include WAV on Windows and AIFF on Apple platforms, typically with a header at the beginning.

Wrong Data bits, mode, Latch Edge, or Enable Pulse settings cause decode failure. For channel-prefix differences, see Settings.
