To receive the data you can use the socket notifications. In the palm database there is a same code ( New Socket Notification in Palm OS Garnet, version 5.4.0. ). These notifications are something similar as a interruption attention system. Each time rhat a packet arrives the system will call the function you have written to receive the message and eventually process them, aknoledge them..... Tou dont have to worry in your "main thread" about calling this function. The OS does it for you. In order to play the received data you will have to use the sound system. I do not know much about that

Actually the confusion is * how to simultaneously record and stream data.!! *secondly..how to play the received data simulataneously as its arriving.
