Length
Intro themes of 10 to 30 seconds, stings of 2 to 5 seconds and an outro of 20 to 60 seconds.
Levels and loudness
Apple recommends podcasts target around -16 LUFS integrated. Keep music beds well under the voice, and leave the theme a little louder only when nobody is talking.
Licensing
Paid plans cover use in podcasts distributed on any platform, including ad-supported shows. The full terms are on the licensing page.
A workflow that works
- Write a prompt for the main theme that names your show’s tone
- Reuse the same instruments and key in prompts for stings and beds
- Trim and fade in your editor
- Save the prompts so every future episode can match
Avoid themes that are too long. Listeners skip intros, so 10 to 20 seconds usually serves the show better.
Prompts for podcasts
Warm podcast intro theme, 20 seconds, acoustic guitar and soft synth, friendly and curious, ends on a clean chord
Three-second transition sting in the same style, acoustic guitar strum and a soft shaker
Low-key background bed for an interview podcast, mellow keys and light percussion, no melody
