Here's my {{{rec2.wav}}} looks like in the WAV analyzer: 155 155 156 [[Image(rec2.png, 50%)]] ]156 [[Image(rec2.png, 50%)]] 157 157 158 158 And in my measurement, I measured the delay is about 200 milliseconds. This value is only for the first play/echo cycle, and as most buffers in pjmedia are adaptive, the latency may grow or shrink dynamically as time progresses, hence it's probably better to use {{{latency.c}}} to measure the latency in more precise manner.
