Dear community,

are exports expected to be latency-compensated? E.g., is audio expected to =
be
at the same positions as in the sources (given there is no intentional dela=
y)?

In Ardour 6.9.0, I observe that the more plugins on a track/bus, the later =
the
audio in the exported file. [1] This can cause obvious problems. E.g. a) wh=
en
multiple tracks have different plugin-introduced latencies, stem-exporting =
and
re-mixing the tracks. E.g. b) when exchanging updated stems with more/less
plugins than in the stems exchanged before (when others edit, their edits a=
re
misaligned then). I tried the regular and stem export with the same results=
.

This is a simplified test setup:

track A -> bus "unproc" (no plugins) -> master
track A -> bus "proc" (e.g., Calf Comp., Multiband, Limiter) -> master

Stem export to wav with "apply processing" enabled. Exported audio from bus
"proc" and master is later in the export than from bus "unproc". Ardour doe=
s
not report the latency to be ambiguous. "Disable PDC" is inactive.

Anything I miss or don't understand? Is non-latency-compensated export mayb=
e
desirable as well in some cases?

Thanks in advance and regards

Lukas
