Das WAVE-Dateiformat ist ein Containerformat zur digitalen Speicherung von Audiodaten, das auf dem Resource Interchange File Format (RIFF) aufsetzt, das von Microsoft für das Betriebssystem Windows definiert wurde.

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.

Waveform Audio File Format (WAVE)
The following is taken from RIFFMCI.RTF, "Multimedia Programming Interface and
Data Specification v1.0", a Windows RTF (Rich Text Format) file contained in the .zip
file, RMRTF.ZRT. The original document is quite long and this constitutes pages 83-
95 of the text format version (starting on roughly page 58 of the RTF version).

WAVE File Format is a file format for storing digital audio (waveform) data. It supports a variety of bit resolutions, sample rates, and channels of audio. This format is very popular upon IBM PC (clone) platforms, and is widely used in professional programs that process digital audio waveforms. ...

Wave Files are read using the struct and wave modules. The two modules are part of standard Python library. I also use the scipy io module to show another method of reading into the more efficient numpy arrays.
