AI music for audiobooks

Most audiobooks use music sparingly: an opening theme, short chapter transitions and closing credits. When it does appear, it should set the book’s tone in a few seconds.

Prompt for audiobooks0/600

Length

Openings of 10 to 30 seconds, chapter stings of 3 to 8 seconds.

Levels and loudness

ACX (Audible) requires narration between -23 and -18 dB RMS with peaks no higher than -3 dB, so keep any music within those limits too.

Licensing

Paid plans cover use in audiobooks sold on any platform. The full terms are on the licensing page.

A workflow that works

  1. Pick instruments that match the book’s genre
  2. Generate an opening theme
  3. Create short stings in the same key
  4. Leave narration itself unscored unless the publisher wants it
Avoid music under long narrated passages. Listeners find it tiring over hours.
