Maybe this is a little off-topic but i really need help. im stuck for days. Im making a real time audio stream programm with sockets in java. The following code parts are client and server. The client sends audio stream to server,and the stream is playing to my server speakers. I need to do the opposite. Stream audio from server to client's speakers. How to reverse those code parts so to achieve that? im really confused
