I already have the chat program done, now I need to add audio to the program

Please write program code for audio

Goal:Chatting with someone requires the use of SMS text messaging or a server-based Instant Messenger (IM) service such as Skype or Google. What if you want to chat with someone that is nearby (that is, within the same room or otherwise within the same WiFi hotspot or Ethernet domain that you are part of)? Why use a third-party and/or heavyweight service such as Skype or Hangouts? For your first project you will develop a "local chat" program whereby you can chat directly with a nearby user and implement it in a Windows, Linux, or Android application program. The "local chat" program should be implemented using a client/Server model based on UDP protocol. Requirements: The requirements of this "local chat" program must meet are: 1The chat is performed between a client and a server. 2The server will first start up and choose a port number. Then the server prints out its IP address and port number. 3. The client then will start up and create a socket based on the information (IP address and port number) provided by the server. 4. Now the client and the server can chat with each other by sending messages over the network. 5The client/server Musr be able to communicate with each other in a continuous manner. (e.g. One side can send multiple messages without receiving any replies from the other side 6. There is no requirement on what language you use to implement this project, but your program should call upon the socket API for UDP to realize the functionality
