The SourceForge project and wiki describe it as software that analyzes MP3 files and adjusts them losslessly to a target volume. Unlike simple peak normalization, it uses statistical loudness analysis intended to match how loud the file sounds to a human listener, then changes the MP3 data directly without decoding and re-encoding. ### Project history That technical choice gave MP3Gain its durable niche: it makes volume changes available to players that do not understand ReplayGain tags, while avoiding the generational loss of re-encoding. The project page also distinguishes the original MP3Gain from similarly named software that normalizes inside a track by re-encoding, emphasizing that MP3Gain's own changes are reversible in the classic workflow. ### How it is used The ecosystem around MP3Gain became broader than the command-line engine. SourceForge lists it in audio analysis and audio mixer categories, carries long-running discussion and ticket activity, and points users toward related frontends such as QMP3Gain and easyMP3Gain. Homebrew packages it as a lossless MP3 normalizer with statistical analysis, while other package managers and Windows-oriented manifests preserve it for users who need batch loudness adjustment of existing MP3 libraries rather than a modern tag-only loudness workflow. ### Sources - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** mp3gain - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Debian apt - mp3gain - 1.6.2-2+b1: normalized package name match | Debian stable package indexes: mp3gain from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Lossless mp3 normalizer with statistical analysis | http://mp3gain.sourceforge.net/ - Nix - mp3gain: normalized package name match | nixpkgs package indexes: pkgs/by-name/mp/mp3gain/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - mp3gain - 1.6.2-2build1: normalized package name match | Ubuntu 24.04 LTS package indexes: mp3gain from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Lossless mp3 normalizer with statistical analysis | http://mp3gain.sourceforge.net/ - apk - mp3gain - 1.6.2-r4: normalized package name match | Alpine Linux edge package indexes: mp3gain from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | Analyze and adjust the volume of MP3 files | https://mp3gain.sourceforge.net/ - dnf - mp3gain - 1.6.2-17.fc44: normalized package name match | Fedora Rawhide package metadata: mp3gain from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/e5ca8ce900cd68f5419e1c39ae517343100b306336cbaeb70a3c153121d95094-primary.xml.zst | Lossless MP3 volume adjustment tool | http://mp3gain.sourceforge.net/ - zypper - mp3gain - 1.6.2-3.6: normalized package name match | openSUSE Tumbleweed package metadata: mp3gain from https://download.opensuse.org/tumbleweed/repo/oss/repodata/be8d3611d25469107f32075a1697e69ec57a2b850b42348a658cc671ad5ec2b50760d02c3e59524d50da9a11d5be799bdaffba2e166e8ca8858512e3c0bd665d-primary.xml.zst | MP3 Volume Normalizer based on Replay Gain | http://mp3gain.sourceforge.net/ - Chocolatey - mp3gain: normalized package name match | Chocolatey community package catalog: mp3gain from http://community.chocolatey.org/api/v2/Packages?$filter=IsLatestVersion&$select=Id&$top=1000&$skiptoken='7.9764','inconsolata' - winget - GlenSawyer.MP3Gain: normalized package name match | Windows Package Manager source index: GlenSawyer.MP3Gain from https://cdn.winget.microsoft.com/cache/source.msix ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Media and graphics packages](https://www.automicvault.com/pkg/media-graphics-tools/) - Matched media, image, audio, video, or graphics metadata. - [Homebrew utility packages](https://www.automicvault.com/pkg/brew-utility-packages/) - Matched Homebrew package provider. - [mpg123](https://www.automicvault.com/pkg/brew/mpg123/) - Runtime dependency declared by Homebrew. - [mp3cat](https://www.automicvault.com/pkg/brew/mp3cat/) - Shares av.db curated category or tags: audio, cli, media, mp3, utilities. - [mp3check](https://www.automicvault.com/pkg/brew/mp3check/) - Shares av.db curated category or tags: audio, cli, media, mp3, utilities. - [mp3splt](https://www.automicvault.com/pkg/brew/mp3splt/) - Shares av.db curated category or tags: audio, cli, lossless, media, mp3. - [abcde](https://www.automicvault.com/pkg/brew/abcde/) - Shares av.db curated category or tags: audio, cli, media, mp3. - [clamz](https://www.automicvault.com/pkg/brew/clamz/) - Shares av.db curated category or tags: audio, cli, media, mp3. - [easy-tag](https://www.automicvault.com/pkg/brew/easy-tag/) - Shares av.db curated category or tags: audio, cli, media, mp3. - [ebook2cw](https://www.automicvault.com/pkg/brew/ebook2cw/) - Shares av.db curated category or tags: audio, cli, media, mp3. - [id3lib](https://www.automicvault.com/pkg/brew/id3lib/) - Shares av.db curated category or tags: audio, cli, media, mp3. ## Combined YAML source View the package source record on GitHub.
