iVolume
iVolume is a Mac audio utility that analyzes songs in Apple Music or iTunes and normalizes playback volume across your music library.
What is iVolume?
iVolume is a music volume normalization app for Mac that helps keep songs in your Apple Music or iTunes library playing at a more consistent loudness. It analyzes each track with a loudness algorithm based on perceived human hearing and writes updated Sound Check information so playback levels are better balanced. This is useful for shuffle listening, playlists with mixed sources, party music, and albums that otherwise jump sharply in volume from song to song. The app supports common formats such as MP3, AAC/M4A, AIFF, and Apple Lossless, and it can also preserve album-level consistency for records that should stay balanced as a whole. iVolume is published by Manfred Schwind Software and is designed for users who manage local music libraries on macOS.

Safety overview
Status: Mostly safe
iVolume is a legitimate music utility whose behavior matches its purpose: it reads your music library, analyzes audio loudness, and updates playback-related metadata used by Apple Music or iTunes. Because it works directly with your song metadata and library information, users should make sure they want those volume-related tags changed before running a full-library scan. If you keep a carefully managed local music collection, it is sensible to maintain a backup before batch-processing tracks.
Recommendation: Keep iVolume if you use Apple Music or iTunes with a local library and want more consistent song volume. If you no longer manage music this way, you can remove it without affecting macOS itself, though any convenience it provided for balancing playback levels will be gone.
