Hi all, The round-trip delay meter mentioned recently on jackit-devel is now available at <http://users.skynet.be/solaris/linuxaudio> The tarball is just 2.6k, so you won't waste much bandwidth :-) Jdelay is a JACK client that measures the delay between its output and input, assuming the channel in between has a linear phase response (i.e. delay is independent of frequency). If you connect it to your soundcard and make a loopback from out to in, it will give you the round-trip latency of your system. Precision is around 1/1000 of a sample if you have a decent sound card. Even in adverse conditions (S/N ratio reduced to 0 dB by adding white noise) it will still measure the delay to within 1/10 of a sample. Enjoy ! -- FA
