CHAPTER 7 AUDIO DEMONSTRATIONS: SHORT-TIME FOURIER TRANSFORM 
			        ANALYSIS AND SYNTHESIS

-------------------------------------------------------------------
Audio Demo 7.1: Time-scale modification of speech signal
		  - Variation of the least-squared-error (LSE) synthesis
		    approach


Time-scale compression
----------------------
LSE.tsm_fast.16k		     File contains:
				       a: Original 
				       b: Reconstruction (no modification)
				       c: Four cases with increasing compression


Time-scale expansion
----------------------
LSE.tsm_slow.16k  	             File contains:
				       a: Original 
				       b: Reconstruction (no modification)
				       c: Four cases with increasing expansion

Audio Demo 7.2: Illustration of human whistle
	  	  - Shows need for good time and 
		    frequency resolution
