LUFS Mastering
music
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 processes WAV, MP3, and FLAC files directly in your browser using ITU-R BS.1770-4 β the same loudness standard Spotify, Apple Music, and DistroKid measure against β so your master hits -14 LUFS and -1 dBTP True Peak before you distribute, not after Spotify turns it down.
- No account, no server upload, no waiting β your audio never leaves your device, which matters for unreleased tracks, client work, or anyone uncomfortable uploading stems to a third-party cloud tool.
- Most mastering plugins require DAW routing, bounce chains, and manual gain staging; LUFS Mastering skips all of that β drop your file, get a compliant master back in seconds, move on to the next track.
- If you're releasing through DistroKid, CD Baby, Tunecore, or LANDR, submitting a file already sitting at -14 LUFS integrated loudness removes the guesswork around normalization and keeps your mix exactly how you intended it to sound at playback volume.
- Deterministic DSP means the output is predictable and repeatable β run the same file twice, get the same result β which makes LUFS Mastering reliable enough for professional producers and freelancers delivering consistent masters to multiple clients or labels.
