Level your library's volume differences to Apple Music's reference. It writes Sound Check tags without changing the audio. Non-destructive, reversible. Analysis is free. MatchVolume levels the volume differences between the tracks in your library to the same reference as Apple Music (about -15.83 LUFS). It analyzes each track's loudness using EBU R128 (LUFS) and writes a Sound Check tag (iTunNORM) to the file — so the audio itself is never altered (non-destructive), and you can revert at any time. What it does • Analyze the loudness of every track (free) • Preview the recommended gain and listen before you commit (free) • Level playback volume by writing Sound Check tags • Per track, or per album (preserving the relative differences between tracks) • Carries over to iPhone, iPad, and Apple TV via your iCloud Music Library • Automatically skips cloud-only, DRM, Apple Music, and purchased tracks, as well as effectively silent ones • Overrides existing Sound Check values with high-accuracy ones, and reverts in one click Trial and purchase Analysis, prediction, and preview are free for your entire library. In the trial you can apply gains to any 10 tracks; the full version (a one-time purchase) unlocks applying to your whole library. Turn on Sound Check in the Music app to hear the leveled playback.
