Where is jack_delay?

I’m trying to set up my system for live processing audio and I’d like to measure round-trip latency. This is commonly done using the jack_delay (or jack_iodelay) program. However, I’ve been searching high and I’ve been searching low, yet I cannot find it in any Fedora repo. These programs seem to be included with the JACK package on other distributions.

Does anyone know where I can find them?

Thanks for any pointers!

I’am not sure if you look for that:


sudo dnf list "jack*"

jack_iodelay is in jack-audio-connection-kit-example-clients. Not sure why this package is no longer being built in F38.

I found rhbz#2203789 which may be related, but doesn’t explain why the package is just gone with no replacement path offered for the 30+ programs. I suggest you follow up there or file a new bug, to show that there is demand for it.

jack_delay is a separate program, not from JACK upstream. Source is on Fons Adriaensen’s site (see downloads).

There’s a spec file in Audinux repo, but it hasn’t been built in a while. Maybe you want to bring it back? Contributions welcome.
