I just finished implementing the xspf flash player on KJZZ.org!
In looking at the developer’s forum, I found that cetra3 created a version which includes a Seek Button and play bar, which allows people to view where they are in an audio file as it is playing – as well as allows people to select where in an audio file they would like to listen.
I am not sure how close this is to WNYC’s audio player. I had an issue with their player not recognizing the xspf playlists as they were dynamically generated for each story (some weird 404 error in the header — likely more an issue on my end than theirs).
Thought you might find this interesting.
For example, here’s an audio story from KJZZ’s recent Chandler Roundup Series.
