What is a 100KB WAV file useful for?
A 100 KB WAV is an uncompressed audio file suitable for testing the basic WAV RIFF header parser, audio player support for raw PCM content, and upload validator MIME type detection (audio/wav or audio/x-wav). At 44.1 kHz 16-bit stereo the file is only about 0.6 seconds — use it for unit tests that verify header parsing and format detection without needing a long audio track. It is also the right file for testing that your pipeline accepts WAV and can determine the PCM format from the fmt chunk.
What's inside this file?
Generated by ffmpeg or the Python wave module. A 440 Hz sine tone approximately 0.6 seconds long at 44.1 kHz, 16-bit PCM, stereo. RIFF/WAV container with a fmt chunk (wFormatTag: 1 = PCM, nChannels: 2, nSamplesPerSec: 44100, wBitsPerSample: 16, nBlockAlign: 4) and a data chunk containing raw interleaved 16-bit signed integer samples. No metadata chunks (no INFO LIST, no ID3 embedded tag).
