Perhaps this could be useful for other users of TRX. I left aside the overhead for RTP as I was not sure about the size. Kind regards and thank you for that great piece of code Chris SAMPLE RATE 48000 ---------------------------------------------------- FRAME SIZE LATENCY[ms] OH UDP/IP 120 2.5 64k 240 5 32k 480 10 16k 960 20 8k 1920 40 4k 2880 60 2.667k SAMPLE RATE 24000 ---------------------------------------------------- FRAME SIZE LATENCY[ms] OH UDP/IP 60 2.5 64k 120 5 32k 240 10 16k 480 20 8k 960 40 4k 1440 60 2.667k SAMPLE RATE 16000 ---------------------------------------------------- FRAME SIZE LATENCY[ms] OH UDP/IP 40 2.5 64k 80 5 32k 160 10 16k 320 20 8k 640 40 4k 960 60 2.667k SAMPLE RATE 12000 ---------------------------------------------------- FRAME SIZE LATENCY[ms] OH UDP/IP 30 2.5 64k 60 5 32k 120 10 16k 240 20 8k 480 40 4k 720 60 2.667k SAMPLE RATE 8000 ---------------------------------------------------- FRAME SIZE LATENCY[ms] OH UDP/IP 20 2.5 64k 40 5 32k 80 10 16k 160 20 8k 320 40 4k 480 60 2.667k
