Streaming services like Spotify, YouTube Music, and Apple Music adjust loudness during playback. LUFS Converter Pro brings your tracks to a fixed, measurable target level before upload – no trial and error.
What Spotify does to your loudness
For most playback, Spotify aims for roughly -14 LUFS. If your track is louder, Spotify turns it down. If it is quieter, Spotify may turn it up – which becomes a problem when peak levels are too high and clipping occurs.
The Spotify preset in LUFS Converter Pro
Select Spotify / YouTube (-14 LUFS) in the app. The preset sets:
- Target LUFS: -14
- True Peak: -1.0 dBTP
You can change True Peak afterwards (-0.5 / -1.0 / -2.0 dBTP). For streaming uploads, -1.0 dBTP is a solid balance: enough loudness with some headroom against clipping.
Workflow in the app
- Add source folder(s) under Source folders → Add (multiple folders and subfolders supported)
- Optionally choose a destination folder – otherwise files are replaced in place and originals are backed up in
_original - Select the Spotify / YouTube preset
- Start normalization – first measure, then adjust
- Review the report after the run (filename starts with
lufs_report_)
Trial vs. full version
The free trial processes up to 5 tracks × 40 seconds – presets and two-stage normalization are fully testable. Full albums or large podcast archives need the full license.
