This preserves audio quality while achieving permanent volume changes. Features - CLI lossless AAC bitstream gain : re-encode-free global gain rewrite for AAC/M4A — replacing the long-abandoned aacgain, with -u undo (foobar2000's GUI equivalent has no undo path) - Lossless & Reversible : No re-encoding, all changes can be undone (MP3 and AAC) - ReplayGain : Track and album gain analysis for MP3 and AAC/M4A, with standard REPLAYGAIN tags written alongside the bitstream change (APEv2, ID3v2 TXXX, or MP4 freeform) - Zero dependencies : Single static binary (no ffmpeg, no mp3gain, no aacgain) - Cross-platform : macOS, Linux, Windows (x86 64 and ARM64) - mp3gain / aacgain compatible : Drop-in replacement with identical CLI - GUI Application : Native desktop app for drag-and-drop workflow Installation CLI ( mp3rgain ) Platform Command ---------- --------- macOS brew install M-Igashi/tap/mp3rgain Windows winget install M-Igashi.mp3rgain Arch Linux (AUR) yay -S mp3rgain-bin Ubuntu 25.10 (PPA) sudo add-apt-repository ppa:m-igashi/mp3rgain && sudo apt install mp3rgain (amd64/arm64) Debian sudo apt install ./mp3rgain amd64.deb (download) (ARM64 also available) Nix/NixOS nix profile install github:M-Igashi/mp3rgain Docker docker pull ghcr.io/m-igashi/mp","default_branch":null,"files":null,"tree":[],"storefront":"/r/M-Igashi","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/M-Igashi/mp3rgain/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
