winget install --id=M-Igashi.mp3rgui -e mp3rgui is a graphical user interface (GUI) for mp3rgain, designed to provide an intuitive and efficient way to normalize MP3 volume losslessly. It allows users to adjust audio levels without re-encoding files, preserving quality while achieving consistent playback volumes.
Key Features:
Audience & Benefit: Ideal for audiophiles, DJs, and music enthusiasts who need accurate and reversible volume normalization. Users benefit from consistent listening experiences across different tracks or albums, without compromising audio fidelity.
Lossless MP3/AAC volume adjustment - a modern mp3gain replacement written in Rust
mp3rgain adjusts MP3 and AAC volume without re-encoding by modifying the global_gain field in each frame. This preserves audio quality while achieving permanent volume changes.

A native GUI application (mp3rgui) is available for users who prefer a graphical interface.
Features: Drag-and-drop, track/album analysis, one-click gain application, clipping warnings, progress indicators.
Install: See Installation above for Homebrew, Winget, and AUR options. Binaries are also available from GitHub Releases:

> bash > xattr -cr /path/to/mp3rgui.app >
> This is not needed when installing via Homebrew.
| Option | Description |
|---|---|
-r | Apply Track gain (ReplayGain) |
-a | Apply Album gain (ReplayGain) |
-g <i> | Apply gain of i steps (1 step = 1.5 dB) |
-d | Modify target dB level (use with analysis) |
-u | Undo gain changes |
-k | Prevent clipping |
-R | Process directories recursively |
-n | Dry-run mode |
-o [fmt] | Output format: text, json, tsv (default: tsv if no argument) |
Run mp3rgain -h for the full list of options.
The original mp3gain has been unmaintained upstream since ~2015 (though distribution maintainers continue to apply security patches). mp3rgain is a modern, memory-safe replacement written in Rust.
mp3rgain implements the ReplayGain 1.0 algorithm (89 dB reference level) for full compatibility with the original mp3gain. Loudness values will differ from EBU R128/LUFS-based tools (foobar2000, loudgain, ffmpeg loudnorm).
use mp3rgain::{apply_gain, analyze};
use std::path::Path;
let frames = apply_gain(Path::new("song.mp3"), 2)?; // +3.0 dB
let info = analyze(Path::new("song.mp3"))?;
