What Shape does

See the shape while you listen

The whole track at a glance. Click anywhere on the waveform to play from there, and follow where it builds and where it falls quiet.

Key and BPM, estimated for you

Useful groundwork for a cover or a remix. The Camelot code is shown too, so it drops straight into a DJ workflow.

See what the file has been through
