LUFS Mastering uses deterministic DSP algorithms following the ITU-R BS.1770-4 standard — the same used by all major streaming platforms. Processing happens 100% locally in your browser, so your audio files never leave your device. Perfect for protecting unreleased tracks. Free plan includes unlimited loudness measurement and 2 masterings per day. Credits ($1.49 · 10 masterings) and Pro ($4.99/month · unlimited) unlock batch processing, multi-target export for Spotify and Apple Music simultaneously, saved presets, and mastering history. Also works for AI-generated music from Suno and Udio. Available in 28 languages.
