i'd like to ask for a suggestion for implementing PLC (packet lost concealment).

right now, i don't have PLC applied in my application. when voice data arrive from the network, i just play it right away.

does having PLC require that you play something every interval? like if im expecting a voice packet say every 20ms, then i play something at that rate. either the packet that came off the network, or that if there is none i just pass NULL to the speex decoder and play that one instead.

a simple algorithm wold be very appreciated here. thanks a lot.
