Portable test packs
Create a test pack
Choose a recipe and sample rate to download a local ZIP with WAV signals, settings, a README, manifest and checksums.
Choose a recipe, then generate its deterministic files locally.
Included in every ZIP
- README.mdPlayback, safety and repeatability notes.
- recipe.jsonThe original versioned recipe.
- manifest.jsonSample rate, bit depth, exact parameters and seeds.
- SHA256SUMS.txtChecksums for each portable artifact.
Keep the same versioned reference
A useful comparison retains the signal method, level convention, route, frequency, seed and duration. New finite references use the same generated source for live playback and export at the same sample rate. Older recipes keep their original meaning; long legacy noise playback and old exports may differ. Do not combine an old baseline with a new method as if the signals were identical.

How to interpret your portable test pack results
Settings and method match: A controlled comparison also requires the same output path and listening or capture conditions, apart from the factor deliberately changed.
The method, sample rate or reference differs: Keep the results separate. A different signal cannot establish whether the equipment improved.
A checksum matches: This checks file integrity, not the loudness, acoustic response or quality of the receiving device.
