Testing contract
Reference control- Scenario
- Measure transient positions in the WAV sidecar and compare them with an external edit timeline.
- Expected result
- The mono 8 kHz sidecar lasts 0.725 seconds and exposes deterministic edge transients for variant 09; it is not classified as video.
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.
How to use this file for testing
“Video Sync Audio Reference 09” is a deterministic Novus Examples fixture for Video QA, Audio analysis, Media pipeline testing. Short 270p clips with known scene cuts, freezes, black frames, flash frames, and burned-in captions — for detection and QC tooling.
Documented properties for this file: 8000 Hz. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
Playable creator clips use their measured duration and catalog thumbnail on a watch-first page. Timeline, caption, sync, colour, and failure sidecars remain download-only; compare their ordered decisions and expected outcome rather than assuming every creator format is browser-playable.
