jack_delay can be used to measure the round-trip latency of a soundcard.
To do this, start the program and connect like this:
.
jack_delay -> playback_port -> cable from soundcard output to input ->
-> capture port -> jack_delay
.
jack_delay generates a signal consisting of 13 sine waves, measures the
phase difference between the input and output for each of these, and
computes the delay from those phase differences. The algorithm used is
one developed originally for satellite ranging - that is measuring the
distance between a satellite and a ground station.
