Listen & Label
Press listen while your track plays. It reads the pulse, the tone and the shifts, and maps where the tempo changes. A listen is a reading, not a label.
Put your track on, anywhere in the room, then press listen. Let it run as long as you can: the longer it hears, the more of the track it can map.
The audio never leaves your device. Nothing is recorded, uploaded or stored — only the measurements are shown.
