I have a little problem, and maybe someone can help…
(and hope this is the right place for a question like this)
I always (for years) used ardour and as audiointerface the presonus audiobox 1818vsl. This works perfectly, just “plug and play”.
Now i want to add 8 more mic preamps with the beringer ada8200 (adat mic preamp).
The two devices are synced through adat (presonus as master, behringer as slave).
I get good audio signals, everything works perfect…
EXEPT: the tracks coming from the behringer have a little more latency, (just like 3ms).
Now i have no clue where the problem is or how to solve this.
Maybe it is in the Presonus, like the adat inputs have a different latency than the mic inputs?
Or i suspect that the AD converters in the behringer add the latency.
So: Maybe there is a way to compensate for that in Ardour. Is it possible to apply a different latency compensation in Ardour just for the tracks connectet to the behringer inputs?
That would be great!!
Maybe someone already knows this and has a solution?
And: I use Linux, and Jack…
Otherwise my quick workaround would be to just move the tracks from the beringer in ardour everytime after recording.
Thank you and al the best
Ok… it get’s even more strange…
I did the following experiment:
A square wave from the same source is plugged in one channel of the presonus1818vsl and also in one channel of the behringer ada8200.
I record both channells in ardour. The wave coming from the ada8200 is something like 3ms more late, so out of phase. Now: over time they drift even more apart and very interesting,after every 80 seconds or so, the ada8200 jumps back to being like 3ms late…
