Hello List,
I worked with a (jacklab) VST-capable Ardour version and some free VST -
plugins today and created some kind of a mic- channel strip with a
deesser, eq, compressor, reverb, etc. The problem is: When I bypass the
whole strip voice and music are perfectly synchronized. but when I turn
all the effects on I have a bad latency between the (effect-free) music
and the (channel-stripped) voice. When I use like 50 ladspa eq's,
limiter or whatever at the same time in the same channel the voice in on
time, so I assume that LADSPA plugins are either producing no latency
(which i cannot believe) or there is some kind of a latency management.
Is there something I can do about it (except delaying the other channels
which is basically not possible since the delay changes with the number
of effects)
LADSPA plugins report their latency, and Ardour compensates. Your VST
plugins probably don't report any latency.
Try inserting the "Artificial latency" plugin from the swh-plugins
package after the VSTs and tweak its latency. It doesn't modify the
signal in any way at all, it just pretends that it has a latency so that
Ardour will compensate for it.
