Open a new session
Pick an audio file and give the session a name. The browser draws the waveform pre-upload, so the moment you arrive in the player your pins start landing on the right beats.
Start a session
Drop in a wav, flac, mp3, m4a, ogg, or aac (≤ 500 MB). The browser draws the waveform before the upload so it’s render-ready the moment you open the project.
