Related to my last question, I forgot the key: kAudioUnitConfigurationInfo_AvailableArchitectures that is present in the audio component's ConfigurationInfo dictionary. I'm not 100% sure, but it seems that the plugins built with a Universal architecture fill this array with [x86_64, arm64] while the x86 plugins leave it empty. If confirmed, it could be a way to infer that they run under Rosetta.
