I haven't found any test results yet, at least none audio related. I did
find some testing tools at rt.wiki.kernel.org, but don't know if and how
they could be made relevant to audio low latency testing.
I suppose the most interesting results would come from testing different
kernels with jack/alsa and jack/ffado.
Has anyone done such tests?
There is jack_delay from fons, which can measure the effective overall
latency of your soundcard/drivers/jack/whatever. Plus there is a
"latency.pd" patch that does the same (but with less precision) and
which also features a nice "continuity" measurement, detecting cliks and
dropouts.
best, P
I've must have seen "latency.pd" at some point, but forgotten about it.
Since I use pd almost exclusively I will find it most useful.
I will also have a look at jack_delay.
Thanks.
