Storyteller update #3: Ambient sound

Welcome back to the continuing saga of the development of Storyteller, an interactive, longform theme for Sourcefabric's Newscoop. Read Part 1 and Part 2.
As we promised last week, we managed to get audio files for ambient sound delivery in place this week. It works across the board now on all major platforms and browsers. It's a great feature to have, as it gives an extra sense of depth to the media. I'm also glad that it didn't take as long as I feared it would (we've coded it in three entirely different ways since we started working on the project over two months ago).
We also have chapter introduction panes that help engage readers with a strong graphic and a call to action.
