NPR One: How do I add my Local Segmented Audio?

Your locally-produced segments are a critical piece of the NPR One experience and provide the greatest opportunity for a meaningful connection to the listener.  From news and topical pieces, to longer, contextual features, the mix of national and local segments hopes to provide something for everyone, with the added benefit of listener control. This is the place in NPR One to highlight your best features, audio postcards, and short interviews.

Production Requirements for Stories to Surface in the App

To ensure that your content surfaces in the flow, it must meet the following technical and editorial guidelines.

  • Limit some of your segmented audio to four minutes or less.
  • The first local bucket in the flow has a four minute story time limit - consider editing your more engaging local stories to four minutes and under to ensure they are featured early in the flow.
  • The second local bucket has a local story time limit of 9 minutes and occurs just before the Pledge Audio.
  • The third local bucket has a local story time limit of 12 minutes.
  • Keep in mind that audio that is longer than 12 minutes will not surface as local segmented stories. Please submit longer form audio as podcasts.
