MP3Gain Express
Universal version latest seen at v2.5 · Reported by 5 Macs in the community.
MP3Gain Express is a lightweight audio utility that normalizes the volume levels of MP3 and AAC files without re-encoding, preserving audio quality. It analyzes and adjusts the gain of individual tracks or entire folders to achieve consistent loudness across your music library. The app is particularly useful for people who listen to music from different sources or eras where volume levels vary significantly, eliminating the need to constantly adjust your player's volume. It's a macOS port of the popular cross-platform MP3Gain tool and remains one of the simplest ways to batch-process audio files for consistent playback levels.

You should update to this version immediately from the official download page — it will run natively on your Mac without Rosetta 2 and provide better performance. Your existing library of audio files will work exactly as before.
