An early version of the Sonalize web app, published for testing. It compares two recordings you add and reports how alike they are. Results, scores and features will change before release.

A current version of Chrome, Edge, Firefox or Safari, on a computer or phone. Longer songs take longer on slower devices.

How alike two recordings are, measured from the audio. It is not a finding of copyright infringement: that depends on what is protected, whether the earlier work was heard, and the law where you are.
