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.\n\n## Installation \n\nYou probably just want to know how to install it.\n\n````\ngit clone http://github.com/rickbutton/speaker\ncd speaker\nmvn\n````\n\n## Usage\n\n### Server\n\n````\njava -jar speaker.jar --server --input 1\n````\n\n### Client\n\n````\njava -jar speaker.jar --client\n````\n\nGo to [the options][options] to learn more about the possible command line flags.\n\n## Challenges\n\nThe 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.\n\n[options]: https://github.com/rickbutton/speaker/wiki/Options\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frickbutton%2Fspeaker","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frickbutton%2Fspeaker","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frickbutton%2Fspeaker/lists"}
