What is a .wav file?
WAV (Waveform Audio) is a RIFF-based container that typically holds uncompressed linear PCM audio, though it can wrap other codecs. Because samples are stored raw, files are large but lossless and simple to read, with configurable sample rate, bit depth, and channel count. It is the standard format for high-fidelity and intermediate audio.
How to use this file
Use an example WAV to test PCM decoding, sample-rate and bit-depth handling, waveform rendering, and audio pipelines that need a lossless reference source.
