I tried to calculate the latency of my system summing up all pd-buffers,
driver buffers, DACs and ADCs latency (given by the manufactorer) but,
compared to the measured latency (analog loop-back) I get a difference
of ~1.5ms (@fs=48kHz). Thus, I wonder what do I wrong and how to
calculate which latency of a system which predicts the correct
measurable latency.
Has anybody done a latency calculation and compared it to the measured
latency?
