WAV (Waveform Audio) is a popular format for storing a digital audio bitstream.

The AudioTools[Read] and AudioTools[Write] commands can read to and write from this format.

There are multiple sub-formats of WAV files, but the two most common are PCM (sub-format 1) and ADPCM (sub-format 2).

Both PCM and ADPCM WAV files can be read by AudioTools[Read].

PCM WAV files can be written by AudioTools[Write].

The general-purpose commands Import and Export also support this format.
