Your WAV stays local.

This implementation reads the supported WAV you choose and measures its samples in a local worker. It sends no audio, filename, waveform, level, duration or sample-rate data to a server. The app stores no file or measurement in cookies, local storage or a database. Temporary browser objects are cleared when replaced, cleared or the page is left.

The optional 3D scene uses the same derived peak bins as the native envelope, and runs locally using a pinned Three.js bundle. No automatic animation, microphone permission, device calibration or external media/asset request is needed. The Three.js MIT license is retained.

Local usage event names carry no file details or measurements. No remote collector, advertising script or affiliate integration is connected in this version. Your browser may manage memory, caching, restored form values and downloaded reports itself.

The manually downloaded report includes numeric measurement and scenario values but no source filename or waveform bins. It remains where you save it. It does not certify perceived loudness, LUFS, true peak, privacy or audio quality.
