Hi!
https://docs.juce.com/master/classAudioProcessor.html#ac1d1db605c16ab803fadd100bb6ff2e8
the doc for processBlock(AUdioBuffer<double> &) is basically the same as for the <float> side, which makes sense. But if it had a reference to like “In order for this to be called, your audio processor also has to override supportsDoublePrecisionProcessing to return true” I would have not had to dive into the VST3 wrapper code! So just figured I’d suggest adding that.
Thanks so much!
