About Earpiece

Earpiece is a self-contained sound recognition lab. Audio is analyzed entirely inside this browser tab — nothing is uploaded, recorded, or sent anywhere. Close the tab and every byte is gone.

How it works

What Earpiece is not

It is not a fingerprint database. It will not name a specific song or a specific bird species. It identifies the character of a sound — its texture, shape, and feel.
