audio-metadata

audio-metadata is a library for reading and, in the future, writing audio metadata.

Why another audio metadata library? / Why not just use mutagen et al?

Clean and understandable code, nice API, and good UX (user experience) are the focal points of audio-metadata. One or more of these things I feel are lacking from already existing alternatives enough to want to write something from scratch with them in mind. Also, there are certain features not present in other solutions that would be prohibitively painful to add.

So, why should I use it?

Features and functionality that set it apart:

• Uses the Python standard load(s)/dump(s) API.
  • Can load filepaths, os.PathLike objects, file-like objects, and bytes-like objects.
• Metadata objects look like a dict and act like a dict.
  • Some common libraries shadow the representation of a dict and/or dict methods but do not behave like a dict.
  • Supports attribute-style access that can be mixed with dict key-subscription.
• All metadata objects have user-friendly representations.
  • This includes humanized representations of certain values like filesize, bitrate, duration, and sample rate.

>>> import audio_metadata

>>> metadata = audio_metadata.load('05 - Heart of Hearts.flac')

Installation

pip install -U audio-metadata

Usage

For the release version, see the stable docs.
For the development version, see the latest docs.

The high-level API and basic usage are covered, but more advanced features/functionality need documentation.
