JACK latency meter
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.
