Recommended maximum file size: 1 GB
If your file is larger than 1 GB you can still attempt to upload it to the NetGalley SFTP. If you receive any error when the file imports, please reach out to us using the Contact Us form so we can help.
File Format:
Audiobook files must be delivered to NetGalley as a zip file, with mp3 chapter files inside.
File Names:
- Your Audiobook file (.zip) must be named with the audiobook ISBN number that exactly matches the corresponding NetGalley title record with no spaces, dashes or letters, like this: 9781111111111.zip.
- Inside the zip file, your mp3 files must be named with the listening order (in three-digit format) at the beginning of the file name, including leading zeros. For example, if chapter two in the audiobook zip file is the third file that should be played, the file might be named: 003_Chapter 2.mp3.
Listeners will see text displayed based on these file names. Note: ISBNs and underscores are removed. If you name your file like the example below, listeners will see "001 Opening" while listening to track one, for instance. This display text is optional.
- No other files should be included in the zip file - no cover image, no manifest, no excerpt.
Bitrate Requirements:
All the mp3 files should have the same bitrate.
NetGalley will reduce the bitrates of the files we receive. The files that NetGalley members receive are between 64-128kbps.
There is no minimum bitrate, but we recommend 64 kbps(kilobits per second) for most files. If you have a full cast recording or other highly-produced audio, 128 kbps is recommended.
Where to Deliver Files:
You must upload your audiobooks via the Deliver Files Page, or via the SFTP.
