speaker is an application that turns a bunch of computers/embedded systems/toasters into a mesh of synchronized speaker outputs. This is the more advanced version of pressing PLAY on a large number of MP3 players all at the same time, hoping that they don't get out of sync, or god forbid, you didn't press them all at the same time.
You probably just want to know how to install it.
git clone http://github.com/rickbutton/speaker
cd speaker
mvn
java -jar speaker.jar --server --input 1
java -jar speaker.jar --client
Go to the options to learn more about the possible command line flags.
The real challenge that speaker tries to conquer is to get near perfect audio synchronization (the human ear can detect differences less than a few dozen milliseconds) over an unreliable network. Because of network latency, it is pretty much impossible to merely play two streams of music without delay. Even on a local network, or even the same machine, there is a large non-negligble amount of latency between the sending of the audio data and the decoding step.
