overview
Small script to create mp3 torrents out of FLACs
history
whatmp3 is a niche Python command-line tool for transcoding FLAC directories into lossy audio formats and optionally creating torrent files for the results. The README describes it as a tool that takes top-level directories of FLAC files, creates new directories for the requested formats, and can create torrents with mktorrent.
The GitHub repository was created in January 2010, placing whatmp3 in the era when private music trackers and local lossless libraries commonly used FLAC as the archival source while distributing additional lossy encodes for compatibility.
Release metadata shows tagged versions 3.6 in 2015, 3.7 and 3.8 in 2016, and 3.9 in January 2025. The long gap and narrow README scope suggest a specialized workflow tool maintained for users who already understand the FLAC-to-torrent release process.
whatmp3's adoption appears concentrated in a small music-archiving and tracker-adjacent niche rather than broad media conversion. Its source-backed usage model specifically mentions zeropadded track numbers, ReplayGain, mktorrent, and private tracker torrent creation, all of which point to reproducible release preparation rather than casual one-off conversion.
Users pass one or more FLAC album directories and request target formats such as MP3 or Ogg Vorbis. whatmp3 detects CPU cores for simultaneous transcoding by default, can apply ReplayGain, writes output directories named for the source and format, and can create private torrents using a supplied announce URL.
The README notes that most behavior is controlled by command-line options, while adding new formats requires editing the script itself. That makes it more of a purpose-built release-preparation script than a general media-transcoding framework.
whatmp3 is package-nerd significant because it captures a very particular Unix media workflow in one command: start with archival FLAC, generate distribution encodes, preserve metadata, and emit torrent artifacts. It is not trying to replace ffmpeg or a full tag editor; it glues the established command-line tools together for a community-specific job.
