Repeatable comparisons
Audio test recipes.
Compose a known signal, a controlled action and a recorded observation into a reusable local check.
Local recipe library
Build repeatable checks.
Recipes, settings and observations stay in this browser unless you explicitly export the small JSON recipe file.
Built-in recipes are ready to run or copy into your local library.

instruction step
Set a safe repeatable level
Use a low, comfortable volume. Keep the same output device, cable and volume setting whenever you rerun this recipe.
StatusWeb Audio is unavailable in this browser.
Execution contract
One recipe, one result model.
Versioned
Every file declares its schema version. Unsupported future files are declined clearly rather than guessed at.
Safety checked
Imports reject unsafe levels, durations and frequencies; they are never silently changed.
Entitlement neutral
Any future library can use the same playback settings, validation and local observation result.
