mp3rgain

Lossless MP3/AAC volume normalizer, a modern replacement for mp3gain

Desktopfreeglobal

mp3rgain is a free, open-source CLI tool that losslessly normalizes MP3 and AAC volume by adjusting gain metadata rather than re-encoding audio, serving as a modern Rust-based replacement for the older mp3gain and aacgain tools. It's aimed at people normalizing volume across a music library who don't want to lose audio quality through re-encoding.
