Hello,
I've been trying to improve the ambisonic decoding for a project in
SuperCollider on Arch Linux. Typically I use newCIPIC decoder kernel
from the ATK. As an alternative, I first tried the ambix VST plugin in
Ardour. When I could get it to work I got excellent results, however it
crashed Ardour constantly and the standalone version was equally
unstable. The ambix project seems to have stopped development more than
2 years ago.
I then tried the VST version BinauralDecoder from iempluginsuite. This
works well in Ardour testing with a 2nd order N3D signal. The standalone
version however fails to produce an output and seems to be caught in a
constant internal feedback loop, ie. it shows "INPUT MUTED" when the
audio settings have "Feedback loop: mute audio input" selected and also
produces feedback when set to ALSA (rather than Jack) and the "test"
button selected. This feedback occurs with no input connections in Pipewire.
In SuperCollider (from which would be the ideal platform for me to use
the BinauralDecoder), I again attempted to use the VST version using
VSTPlugin and its associated classes. When however I scan for plugins
with VSTPlugin.search, it prints:
'/usr/lib/vst3/BinauralDecoder.vst3' is black-listed.
I've not been able to find where that blacklist is located. The same
plugin continues to work correctly in Ardour. The version installed of
the iempluginsuite is the latest: 1.13.0-1.
Does anyone have any suggestions?
Merry Christmas,
