App Description
This app powers Improv Everywhere's Mp3 Experiment project. The app will synchronize playback of a custom audio file for all participants who have downloaded it and joined the event. Users simply need to have the app open at the event's start time, and the audio will automatically begin playing in sync.
The Mp3 Experiment is a participatory audio adventure where attendees download an audio file and listen to synchronized secret instructions in a public space. Hilarity ensues as participants carry out ridiculous, synchronized instructions delivered to their headphones via narrator "Steve" and everyone else tries to figure out what in the world is going on.
We stage a new Mp3 Experiment in New York each year and also tour the project to college campuses and festivals around the world.
