Audiobookshelf uses the ID3 metadata tags in audio files to populate data.
Data parsed from the folder structure and filenames takes priority over ID3 tags unless you have enabled the scanner setting "Prefer Audio Metadata".
Metadata on audio files will be mapped as follows (second tag after "/" is a fallback):
| ID3 Tag (case-insensitive) | Audiobookshelf Data |
|---|---|
| artist / album-artist | Author |
| album / title | Title |
| subtitle | Subtitle |
| publisher | Publisher |
| year | Publish Year |
| composer | Narrator |
| description | Description |
| genre | Genres * |
| series | Series |
| series-part | Volume Number |
| language / lang | Language |
| isbn | ISBN |
| asin | ASIN |
| Overdrive MediaMarkers | Chapters** |
* Genre meta tag can include multiple genres separated by "/", "//", or ";". e.g. "Science Fiction/Fiction/Fantasy"
** Chapter extraction from Overdrive MediaMarkers must be enabled in your server settings
Embedded cover art will be extracted and used only if there are no images in the book folder.
