Speakerfy is an app that can crowd source sound in a similar way. Users link a bunch of mobile devices through the app via a WiFi network, and then all those devices play the same audio, meaning you can be in a group and all be listening to the same playlist.

But they aren’t stopping there.

“Video is one of the things we're implementing soon,” Austin Wright with Speakerfy said. “What you do is you have a laptop, you put a smartphone on the left, a tablet on the right and you can have surround sound while camping.”

Speakerfy is also working on a microphone version of the app so that you could be at an ad hoc gathering, like a protest for example, and as the leader speaks into his or her phone to address the crowd, everyone phone in the crowd becomes a speaker, amplifying the message.
