It is a great addition Tom, I'm packaging it in Planet CCRMA now.
I'm trying to see what is the best way to convert the plugin so that it
can deal with first order ambisonics impulse responses. Those are four
channels wide (ie: four convolutions, one for each of the four incoming
channels - W X Y Z).
I managed to get it to work by creating ir-amb.cc, ir-amb_gui.cc, etc,
etc. And changing your code to have the required number of ports, etc.
It does work, except that my simple minded rewrite breaks down if I try
to instantiate a normal IR plugin in addition to the IR-AMB (how I named
the "new" plugin). In that case the second instance (order does not
matter) bugs out with:
(ardour-2.8.12:14284): GLib-GObject-WARNING **: cannot register existing
etc (same for IRModeInd and IRMeter, all the gui classes I did not
I can have multiple instances of either, but not mixed (well, I can, it
is just that opening the gui for the second does not work and crashes
Knowing nothing about all the components involved I need some help... I
can supply or post the patch if needed (I presume it is some simple gtk
thingy I need to add to the code).
