Hi Everybody,

I'm working in an application which enables clients to transmit audio to each other in full duplex. We want to make the system half duplex - what we are going to do is compare the incoming Audio wave to the outgoing, and if the outgoing wave is stronger - we are going to broadcast. If not, (Outgoing < Incoming) then we are going to block it. Is Anyone familiar with algorithm how do such comparison ( what to convert - average, pick ?)

Thanks, Ron

google for voice activity detect. There is also a case where there is a VAD value based on voice volume, the T and R values are compared and the stronger wins...as you described. Bob
