CHAPTER 8 AUDIO DEMONSTRATIONS: FILTER-BANK ANALYSIS/SYNTHESIS

-------------------------------------------------------------------
Audio Demo 8.1: Reverberation in FBS synthesis (Example 8.1)

good_bad_FBS.16k 		     File contains:
				       a: With phase correction (same as original)
				       b: Without phase correction
				       c: Repeated

figure_good_bad_FBS 	             File contains:
				       a: Narrowband spectrogram 
				          with phase correction 
				       b: Narrowband spectrogram
				          without phase correction;
				          shows spectral holes 
				          with reverberation
				

-------------------------------------------------------------------
Audio Demo 8.2: Phase Vocoder 
		  - Time-scale modification and special effects;
		    no phase synchrony invoked

phase_vocoder.16k		     File contains [*]:
				       a: Original
			               b: Slowed-down x2, played back 
				          with D/A resampling
				          (equivalent to effect of 
				          slowing down a tape recorder)
				       c: Time-scale expanded x2 with 
				          phase vocoder
 				       d: Time-scaled compressed with 
				          phase vocoder x2
				       e: Original
	 			       f: Special Effects with phase vocoder
				          (time-expanded, pitch modification, etc.)
