EE4209/EE5809 Digital Audio .wav file format
WAVE PCM soundfile format
The WAVE file format is a subset of Microsoft's RIFF specification for the storage of multimedia files. A RIFF file starts out with a file header followed by a sequence of data chunks.
A WAVE file is often just a RIFF file with a single "WAVE" chunk which consists of two sub-chunks --
i) a "fmt " chunk specifying the data format and
ii) a "data" chunk containing the actual sample data.
Call this form the " Canonical form". Who knows how it really all works.
