YIN / LIVE HISTORY

A pitch curve you can act on

The live history makes intonation drift visible instead of hiding it behind a single number. Hold a note, watch the cents line settle, and adjust your voice without recording audio to a server.

Use it for a focused practice pass

Choose a voice range to reduce octave errors, start the microphone, then sustain one note. The detector withholds weak or unstable readings so the curve stays useful.

Audio is analyzed in this browser only. Nothing is recorded or uploaded.
