About:
iVolume calculates the playback volume of all songs in your music library using advanced Replay Gain analysis. It automatically adjusts track volumes to ensure a consistent listening experience without manual tweaking. This tool integrates directly with macOS and supports various audio formats for comprehensive library management.

Key Features:

Automatic volume normalization using Replay Gain
Batch processing for entire music libraries
Support for MP3, AAC, FLAC, and ALAC formats
Non-destructive adjustment preserving original files
Integration with Apple Music and iTunes

Use Cases:

Standardizing volume across a large, eclectic music collection
Preparing audio files for consistent playback on mobile devices

Alternatives:

MP3Gain – Free, open-source tool focused specifically on MP3 files; less integrated with macOS than iVolume.
SoundCheck – Built-in iTunes feature that normalizes volume but uses less precise analysis than Replay Gain.
