public bool enableSampleFramesAvailableEvents { get; set; }

Depending on how often audio sample frames are drained, the sampleFramesAvailable events may be produced at a high rate. Producing these events may cause a unwanted overhead even if they are not monitored, so they can be disabled.

When sample frames are consumed from a native plug-in, consider using the associated native event handler set via SetSampleFramesAvailableNativeEventHandler.
