Does it keep on increasing or does it just stay at 8% ? liveadder has a
queue that you can control with the "latency" property os it can sync up
the various streams. The default 60ms is chosen to be larger than the
common 40ms packet size for RTP. That said 60ms of 44khz 2 channel raw
audio should only be 10kbytes..
