Interview With Public Radio Tuner Creators Bill Heyman and Damon Allison

Bill Heyman and Damon Allison of CodeMorphic created the Public Radio Tuner. Currently the #1 free audio application, the Public Radio Tuner lets iPhone owners listen to live streams of hundreds of public radio stations.

This interview features detailed instructions for creating streaming applications, and some of the similar-but-different challenges they faced when creating a forthcoming media center application for Cisco.

Finally, we talk about creating “Obamify” — an app that transforms images into those iconic 4-color posters from the campaign — and the problems they ran into getting it into the App Store.
