history

Project history and usage

normalize is a command-line audio file volume normalizer by Chris Vaill. 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
