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.
