Hark

Before we listen

Hark listens for about 12 seconds and builds an acoustic fingerprint on your phone. Only that fingerprint — never the audio — is sent to identify the song.

Your phone will now ask for microphone access.

How Hark works

1. Listen. Your phone records a few seconds of audio — it never leaves your device as audio.
2. Fingerprint. Right here in the browser, Hark turns the sound into a compact acoustic "signature" (a map of the loudest frequency peaks over time).
3. Match. Only that tiny signature is sent to the catalog to find the track. No account, no key, no charge.

Works best with the music playing out loud and clearly. Humming or singing won't match — it recognizes the actual recording.
