void OnBeginDestroy()		NiagaraDataInterfaceAudioOscilloscope.h
void OnUpdateResampling ( int32 InResolution, float InScopeInMilliseconds )	Called when Resolution or Zoom are changed.	NiagaraDataInterfaceAudioOscilloscope.h
void OnUpdateSubmix ( USoundSubmix* Submix )	Called when the Submix property changes.	NiagaraDataInterfaceAudioOscilloscope.h
void PostAudioToGPU()	This function enqueues a render thread command to decimate the pop audio off of the SubmixListener, downsample it, and post it to the GPUAudioBuffer.	NiagaraDataInterfaceAudioOscilloscope.h
