Jack_delay can be used to measure the round-trip
latency of a soundcard.
My M-Audio Audiophile 24/96 PCI card's roundtrip latency at 64|2|44100
(jack 0.118.0 so no -E measurement):
189.623 frames 4.300 ms
The result confirms my favourable opinion of the card's performance in
practice. Thanks for providing the tool to measure it, Fons.
Cheers, Tim
