Browser-generated 44.1 kHz, 16-bit mono WAV fixtures with reproducible PCM samples.

Open local generatorLocal WAV fixtures for waveform, playback, and upload tests
Audio fixtures are generated inside your browser and are never uploaded. The deterministic PCM sampler keeps downloaded WAV bytes and waveform previews reproducible across repeated runs.
Test method
Generate sine, square, noise, and silence WAV fixtures with the same preset twice, then load both into the target player or analyzer.
Validation steps
Validate RIFF/WAVE headers, sample rate, channel count, duration and byte length; compare hashes for deterministic presets and inspect the waveform.
Expected result
Repeated generation yields identical bytes, each waveform is distinguishable, and silence remains on the center line for the full duration.
Failure signals
Treat a bad RIFF length, clipped samples, changed hash, drifting duration, unexpected channel count, or decoder rejection as a failure.
