Frequently asked questions

No. There is no account, no tracking, and no upload step; audio is analyzed locally in your browser.

You choose an audio file, the browser decodes it on your device, and real features are computed from the signal in four steps.

Six measured signal layers: waveform, rhythm, spectrum, harmony, structure, and dynamics.

Some values are estimates and depend on audio quality. Uncertain key, BPM, and section boundaries are clearly labelled.
