WAV Playback Fixture Matrix

Pick WAV fixtures for telephony ingest, playback validation, silence handling, sample-rate checks, and clipping detection.

How to Use This Matrix

Separates telephony, voice-band, stereo reference, silence-led, and clipped waveform cases.
Useful for players, waveform visualizers, speech ingest, and audio normalization pipelines.
Links directly into the media-playback workflow hub and the WAV sample library.

This matrix is anchored to the WAV library page and its manifest.

Variant	Profile	Test Focus	File	Size	Download
Mono 8kHz Tone Good default for narrowband telephony and speech QA paths.	Telephony baseline	Low-rate mono ingest	`wav_mono_8khz_tone_sample.wav`	31.3 KB	Download
Voice-Band 16kHz Useful for voice-processing pipelines that expect 16kHz mono audio.	Speech fixture	Voice ingest and ASR prep	`wav_voice_band_16khz_sample.wav`	78.2 KB	Download
Silence Then Tone Useful for trim logic, waveform markers, and event detection checks.	Playback edge	Leading silence handling	`wav_silence_then_tone_sample.wav`	93.8 KB	Download
Stereo 44.1kHz Mix Good for browser and desktop player verification.	Playback reference	Standard stereo playback	`wav_stereo_44k_mix_sample.wav`	516.8 KB	Download
Stereo 48kHz Reference Useful when pipelines distinguish 44.1kHz from 48kHz sources.	Broadcast-style reference	48kHz ingest and playback	`wav_stereo_48khz_reference_sample.wav`	468.8 KB	Download
Clipping Reference Targets waveform clipping detection, peak limiting, and ingest warnings.	Signal edge case	Clipping detection and normalization	`wav_clipping_reference_sample.wav`	344.6 KB	Download

Audio and video fixtures for browser playback, orientation handling, no-audio behavior, and ingest validation.
