A Python library for reading and writing audio tags: artist, album, cover art and, for FLAC, the real bit depth.
In ToshaMusic it refines the FLAC bit depth when ffprobe reports the container's 32 bits instead of the real 24. The file name and tags are built from measured parameters only.
When files enter a library or catalogue automatically, and their description (artist, album, cover art, quality) must be the truth rather than what the source promised.
In ToshaMusic, after a download ffprobe reads the file's parameters, but for FLAC it often reports the container's 32 bits instead of the real 24. mutagen refines the actual bit depth. The file name is built from measured parameters, for example Artist - Title [24bit-192kHz].flac, and a verification line with bit depth, sample rate, bitrate, cut-off frequency and the bot version is written into the tags.
If files never enter a catalogue and nobody searches them by tags, separate tag handling is unnecessary.
