Thanks for the reply. I think I'm beginning to understand but can you clarify a bit more. 1) I am confused on "trade error-free quality" part. Basically the encoder is doing something to the encoded data by looking at the SPEEX_SET_PLC_TUNING parameter? 2) How does the receiver side determine whether the packet loss occured or not?
