The Inhuman Microphone
From Music Hack Day
This musichackday hack was inspired by Occupy Wallstreet's Human Microphone. Because megaphones are banned at the protests, one person shouts a message, then everyone else repeats it.
 What Happens
Our hack circumvents the “no megaphones” rule. The protester shouts a message into their phone. It gets uploaded to a server. Then it gets sent to the other phones nearby. The phones are synchronised, and then they are all triggered to play the message back at the same time.
 How it works
We created an iPhone app using Phonegap to record and upload the audio (the “protester” in the scenario above).
