DescriptionWhen I analyze the track loudness, using the new LAN feature of 6.3, ardour only shows the peak, not the LUFS.
Screenshot attached.

Subsequently the gain compensation is wrong.

How many output channels does the master-bus have?
The LAN only supports stereo.

Oh I recall that you've reported issues with libardourvampplugins.so in the past with your OS.
Perhaps the analysis plugin isn't found?


Menu > Window > Scripting

paste the following and click "run":
local plugins = ARDOUR.LuaAPI.Vamp.list_plugins ();
for id in plugins:iter () do
    local vamp = ARDOUR.LuaAPI.Vamp(id, Session:nominal_sample_rate())
    local vp = vamp:plugin ()
    print (vp:getIdentifier (), ":", vp:getName (), ":", vp:getDescription ())
end


Does the output show
  dBTP : dBTP Meter : True Peak Meter (4x Oversampling)
  ebur128 : EBU R128 Loudness : Loudness measurements according to the EBU Recommendation 128

Since Ardour 6.3-135-ge76055d63d there's now a popup dialog when the plugin is missing.

@x42 Thanks!

My master bus is stereo.

The script outputs:
```
localcandidatepyin : Local Candidate PYIN : Monophonic pitch and note tracking based on a probabilistic Yin extension.
pyin : pYin : Monophonic pitch and note tracking based on a probabilistic Yin extension.
yin : Yin : A vamp implementation of the Yin algorithm for monophonic frequency estimation.
> OK
```

How do I get dBTP and ebur128 in there?

Is there libardourvampplugins.so installed in ardour's lib/ folder (or in system-wide VAMP_PATH)?

I recall that you're reported a crash since this lib wasn't found or loaded (0008161). Likely this is a follow up issue:

> Since 6.0-35-gfe1f8effb9 optimized builds don't crash anymore, but analysis remains unavailable if the VAMP plugin cannot be loaded.

I have $ARDOUR_PREFIX/lib/ardour6/vamp/libardourvampplugins.so

Where $ARDOUR_PREFIX is the path ardour is inststalled, in my case /nix/store/2hj94jr0z57wivzb2sp0va56n78lhfb3-ardour-6.3/

After removing "--use-external-libs"
 from the build recipe, this issue was resolved.

Can users close an issue,or is that reserved for maintainers?
