LUFS Converter Pro normalizes your files to a fixed LUFS level using the international EBU R128 standard – not via ReplayGain entries in the file. Loudness, peak levels, and dynamics are measured and documented in the report.
ReplayGain
ReplayGain stores a hint in the file telling the player how loud or quiet to play it. The file itself stays unchanged. That works in some players – for Spotify uploads or broadcast it is not enough, because fixed LUFS levels are expected.
LUFS normalization in LUFS Converter Pro
The app works in two steps: first the file is measured, then the level is adjusted precisely – as a pure volume shift without extra compression.
Built-in presets:
- Spotify / YouTube: -14 LUFS
- Apple Music: -16 LUFS
- Podcast / General: -18 LUFS
- EBU R128 Broadcast: -23 LUFS
Practical tip
Have an older library with ReplayGain tags? Normalize once to real LUFS values with LUFS Converter Pro – regardless of player support. Supported formats: MP3, FLAC, and WAV. For FLAC, title, album, and other details are preserved.
