NAME

       jdelay - measure sound card latency

SYNOPSIS

       jdelay

DESCRIPTION

       Jdelay  is a simple JACK application that you can use to measure the latency of your sound
       card. It uses a phase measurements on a set of tones to measure the delay from the  output
       to the input. Accuracy is about 1/1000 of a sample.

       To  use  Jdelay,  first  start  a  JACK server and then start jdelay in a console. It will
       create an input port and an output port. Connect them in some manner  (for  instance  with
       the  QjackCtl patchbay), and check the output on the console to see the delay, measured in
       samples.

SUGGESTIONS AND BUG REPORTS

       Any bugs found should be reported to the upstream author and/or package maintainer.
