Mutagen is a Python library for reading and writing audio metadata (tags) across many formats including MP3/ID3, FLAC, MP4, Ogg, and APEv2. It has no dependencies outside the Python standard library and supports Python 3.10+ on Linux, Windows, and macOS.
Use cases
- read and write ID3 tags on MP3 files
- edit FLAC or Ogg Vorbis metadata in Python
- extract track title and artist from audio files
- calculate MP3 bitrate and length from Xing headers
- batch-update music library tags
- manipulate Ogg streams at the packet level
When to choose
- you need dependency-free audio tagging in Python
- you must support many audio formats with one library
- you need full ID3v2.4 frame support
When to avoid
- you need audio transcoding or playback, not just metadata
- you need a non-Python solution
- GPL-2.0 licensing is incompatible with your project
