What the audiobook metadata editor can change
The editor is designed for cleanup work on local audiobook files. You can update common fields such as title, author, album, genre, publisher, year, comment, and cover art, then download an updated file. It is especially useful when a book looks wrong in an audiobook app because the embedded tags are messy.
Frequently Asked Questions
Does the editor save directly back into the same file?
The editor generates a new downloaded file instead of mutating the original in place, which is safer for cleanup work.
Which save path is supported today?
The browser editor saves MP3 plus common M4B, M4A, and MP4 audiobook files. WAV, OGG, FLAC, AAC, and Opus files can still be inspected in the viewer or extractor.
