Master a track.
Any device. No install.
Drop a WAV or MP3 and Sunset masters it right here in your browser with the EDM foundation chain: gain-stage headroom, de-mud EQ, glue compression, light saturation, low-end mono, and true-peak-safe limiting. Your file is decoded, analyzed and mastered on your machine with the Web Audio API — it is never uploaded, and no part of your audio is POSTed to a server. (The page may use pseudonymous visit and click measurement; browser Do Not Track and Global Privacy Control signals disable it.) Every number below is measured from your actual signal. Hear a free 30-second audition; the full-length WAV export unlocks with the $25 app.
