CHAPTER 13 AUDIO DEMONSTRATIONS: SPEECH ENHANCEMENT

-------------------------------------------------------------------
Audio Demo 13.1: Reduction of background fan noise 
		   - Noise reduction adaptive Wiener filter
		     with adaptivity based on
		     spectral change (Section 13.3.3);
		     all examples below use this 
		     same technique
