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
- The Web Audio API takes 60 short snapshots per second of either your microphone or a chosen file.
- Each snapshot is reduced to ten acoustic features — brightness, tonality, harmonicity, roughness, density, dynamism, depth, presence, air, and energy.
- A heuristic matcher compares the live feature vector against a library of 14 sound archetypes and picks the closest fits.
- A description is composed on the fly from the feature values — no canned templates per archetype.
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.
