Tracks is a complete music production studio that runs entirely in your browser — multi-track recording, piano roll, synths, drums, a real mixer, effects, autotune, and WAV/MP3 export. No download, no account, no paywall. Recent builds add parametric EQ with LUFS metering, group buses, track freeze, SoundFont (.sf2) instruments, automation on anything, time-stretch, Web MIDI, a tempo map, and a session view — the pro-grade stuff usually locked behind a desktop DAW, free in a tab.
