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.
