I'm designing a soundscape piece that will accompany an outdoor theatre performance. Around 40 audience members will wear headphones and follow the actors around a collection of local streets whilst experiencing the soundscape in some sort of rough sync to the performance. The performance will be around 45 minutes long and will visit various points along the route with the audience stopping to see each scene. The idea is that the soundscape runs the entire length, including when the audience walk between scenes. Kind of based on the idea of a sound walk.
My question is about how to implement this. At the moment my solution is for everyone to have an mp3 player with a single track for the whole performance. Then literally have everyone press play at the same time then leave it running with an audience guide leading the group around at the right time.
At the moment this feels kind of crude and was wondering if anyone else had done anything similar in the past like a sound walk, or had an awesome idea to deliver the audio to the audience?
