Syntax
class UAudioAnalyzer : public UObject
Remarks
UAudioAnalyzer performs analysis on an audio bus using specific settings and exposes the results via blueprints.
Subclasses of UAudioAnalyzer must implement GetAnalyzerFactoryName() to associate the UAudioAnalyzer asset with an IAudioAnalyzerFactory implementation.
To support blueprint access, subclasses can implement UFUNCTIONs to expose the data returned by GetResult().
