wav
What is a .wav file?
audio/wav
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 a .wav 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.
Download example .wav files
- 220 Hz Sine ToneA pure 220 Hz sine tone, 3 seconds, 16-bit 44.1 kHz mono — a clean reference signal for level metering, spectrum analysis, and waveform rendering.
- 440 Hz Sine Tone (A4)A pure 440 Hz sine tone, 3 seconds, 16-bit 44.1 kHz mono — a clean reference signal for level metering, spectrum analysis, and waveform rendering.
- 1 kHz Sine ToneA pure 1000 Hz sine tone, 3 seconds, 16-bit 44.1 kHz mono — a clean reference signal for level metering, spectrum analysis, and waveform rendering.
- Frequency Sweep 20 Hz–20 kHzA 5-second linear sweep from 20 Hz to 20 kHz across the full audible range — for testing frequency response, spectrograms, and playback fidelity.
- White NoiseThree seconds of white noise with a flat power spectrum — a reference for testing noise handling, gating, and spectral tools.
- Pink NoiseThree seconds of pink noise with a 1/f power spectrum — the standard reference for loudness and room-calibration testing.
- Leading Silence 1s — 440 Hz ToneA 440 Hz tone preceded by exactly 1 second of digital silence. A direct fixture for auto-trim tools — the tone should start at 1.000s.
- Leading Silence 3s — 440 Hz ToneA 440 Hz tone preceded by exactly 3 seconds of digital silence. A direct fixture for auto-trim tools — the tone should start at 3.000s.
