Most musicians upload to Spotify without knowing tracks get turned down if they exceed -14 LUFS. LUFS Mastering fixes this in seconds. Drop your audio file β WAV, MP3, FLAC β and it masters to exactly -14 LUFS with -1 dBTP True Peak using deterministic DSP (ITU-R BS.1770-4). No upload to any server. No account required. Runs 100% locally in your browser. Built for musicians, producers, and freelancers distributing to Spotify, Apple Music, DistroKid, CD Baby, Tunecore, LANDR, etc.
What to expect from an ideal product
- LUFS Mastering checks and corrects True Peak levels to -1 dBTP directly in your browser β no plugin, no DAW session, no server upload required before you submit to DistroKid or CD Baby.
- Drop a WAV, MP3, or FLAC file and get a master that hits exactly -14 LUFS and -1 dBTP in seconds, using ITU-R BS.1770-4 measurement β the same standard Spotify and Apple Music use to evaluate your upload.
- Distributors like DistroKid and CD Baby don't fix clipping or loud masters for you β if your True Peak exceeds -1 dBTP, your track gets flagged or turned down automatically on playback; LUFS Mastering catches this before it becomes a problem.
- Unlike LANDR or online mastering services that require an account and charge per master, LUFS Mastering runs 100% locally in your browser with no login, no subscription, and no file leaving your machine.
- Producers submitting final mixes can use LUFS Mastering as a last-pass metering and correction tool to confirm True Peak compliance across every track before a full album delivery to any digital distributor.
