The official 0.7.7 README describes it as a tool for adjusting audio files to a standard level, useful for mixed CDs and MP3 collections with varying recording levels. ### Project history The official 0.7.7 README carries a 1999-2005 copyright notice and documents the classic Unix build flow of `./configure`, `make`, and `make install`. Homebrew sources the same 0.7.7 release from the official Savannah/Nongnu release archive. ### Adoption history normalize persists as a low-volume legacy package. Homebrew analytics in July 2026 report 74 installs over 365 days, reflecting a tool kept around for older audio normalization scripts more than active mainstream use. ### How it is used Users run `normalize` on WAV or MP3 files, use batch mode with `-b` to preserve an album's relative track levels, or mix mode with `-m` to bring unrelated tracks toward a common level. The README also documents helper scripts such as `normalize-mp3` and `normalize-ogg` for decode-normalize-encode workflows. ### Why package nerds care normalize is a compact example of pre-streaming-era Unix audio tooling: source tarballs, optional MAD/audiofile/XMMS integrations, RMS-based loudness adjustment, and package-manager preservation of old command-line workflows. ### Timeline - 1999-2005: Copyright range in the official 0.7.7 README. - 0.6: README says a limiter was introduced to reduce clipping. - 0.7: README says direct MPEG audio operation was added through MAD. - 2005-09-14: Official Savannah release archive timestamp for 0.7.7. - 2026-07: Homebrew API reports stable 0.7.7 and 74 installs over 365 days. ### Related projects - MAD, audiofile, XMMS, normalize-mp3, normalize-ogg ### Sources - - - - ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** normalize - **Version Scheme:** 0 - **Revision:** 0 - **Conflicts With:** num-utils - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Nix - normalize: normalized package name match | nixpkgs package indexes: pkgs/by-name/no/normalize/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - dnf - normalize - 0.7.7-35.fc44: normalized package name match | Fedora Rawhide package metadata: normalize from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/e5ca8ce900cd68f5419e1c39ae517343100b306336cbaeb70a3c153121d95094-primary.xml.zst | Adjust the volume of audio files to a standard level | http://normalize.nongnu.org/ - MacPorts - normalize: normalized package name match | MacPorts ports tree: audio/normalize/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Related links - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [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. - [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. - [id3v2](https://www.automicvault.com/pkg/brew/id3v2/) - Shares av.db curated category or tags: audio, cli, media, mp3. - [libsndfile](https://www.automicvault.com/pkg/brew/libsndfile/) - Shares av.db curated category or tags: audio, cli, media, wav. - [mp3cat](https://www.automicvault.com/pkg/brew/mp3cat/) - Shares av.db curated category or tags: audio, cli, media, mp3. - [vorbisgain](https://www.automicvault.com/pkg/brew/vorbisgain/) - Both packages work with overlapping file formats or content types.
