How can I...?
Example 2: A Simple TCP Based Server that allows multiple connections
at once, but sends a random ogg vorbis file to the client. Includes a
simple TCP based client for this server, that connects to the server,
decodes the ogg vorbis audio and plays it back. Components used:pipeline,
SimpleServer,
ReadFileAdaptor,
TCPClient,
VorbisDecode,
AOAudioPlaybackAdaptor
