Last year, Jon Udell and I began experimenting with various techniques for expressing an excerpt of an MP3 file in an URL. Jon has now taken this to a whole new level. Not only has he improved the the URL syntax and the excerpting code, but he’s even gone so far as to use a text-to-speech service to generate intros or identifiers for his clips. He apologizes for some of his hacks along the way, but the results are very cool and show some of the things one needs to do to make things work in the world of varying MP3 players.
