Hi all,
I'm trying to write a simple AUV3 extension that would apply Mozilla's
RNNoise noise suppressor (https://github.com/xiph/rnnoise) to a audio
stream, but I can't seem to get any AudioUnits I build to load.
I built AudioUnitV3Example
<https://developer.apple.com/library/archive/samplecode/AudioUnitV3Example/Introduction/Intro.html#//apple_ref/doc/uid/TP40016185>
(it
says it's out of date, but there doesn't seem to be any other examples) and
can run the OSXFilterDemoApp fine. However, if I try to load the extension
into either AU Lab or GarageBand, it fails with "Result Code: -10863".
I tried putting a NSLog in to AUv3FilterDemo's initWithComponentDescription
method. This shows in Console when I run the OSXFilterDemoApp, but nothing
shows up if I tr to load the extension in AU Lab which makes me believe the
plugin isn't even being instantiated.
Any tips on how to debug or trace what's happening during plugin loading?
Thanks,
Albert
