In-browser loudness analysis

TruePeakLoudness and true peak review

Load a batch, measure LUFS and true peak, and review delivery targets without sending files anywhere. Use it as a review aid, not a certified compliance meter.

Streaming StandardSimple workflow
Start here

Choose your files and start the review

Pick the working style, decide whether you want a target, then add audio. The results view opens as soon as you add files, with the table, charts, and file details laid out at full width.

Audio files and analysis stay in this browser. The review view opens as soon as you choose files, and the queue starts working through them.

This app does not send usage analytics unless the deployment operator has explicitly enabled them; audio and results are never included, even then.

Drop files or folders anywhere
