See what this device is playing

The page stays quiet. It only draws the live sound of this device — speaker, room, or headphone leak. Soft auto-gain lifts quiet rooms. Tracks come from density clustering. No melody? It still draws the noise. It never fakes a tune.

Useful

A song is a sandwich: boom / tune / sparkle. Each instrument gets its own track. Practice one layer instead of drowning in the whole mix.

Why live is hard

Notes stack, pianos ring extra high copies, and the picture keeps moving. The grown-up tool records, then looks.

Piano superpower

If the loudest wiggle is 440 Hz, that is the A key. Find it. Play it. Match it.
