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).

Reading and Writing WAV Files in Python
Bartosz Zaczyński  (Mar 27, 2024)
There's an abundance of third-party tools and libraries for manipulating and analyzing audio WAV files in Python. At the same time, the language ships with the little-known wave module in its standard library, offering a quick and straightforward way to read and write such files. Knowing Python's wave module can help you dip your toes into digital audio processing.
If topics like audio analysis, sound editing, or music synthesis get you excited, then you're in for a treat, as you're about to get a taste of them!
In this tutorial, you'll learn how to:
    Read and write WAV files using pure Python
    Handle the 24-bit PCM encoding of audio samples
    Interpret and plot the underlying amplitude levels
    Record online audio streams like Internet radio stations
    Animate visualizations in the time and frequency domains
    Synthesize sounds and apply special effects
