+## Demonstration
+
+For demonstrating sound in / sound out, I decided to port a portion of a school project from my
+Junior year of college: a crude octave up / down pitch shifter. I added the effect into the same
+hardware test design and made it controllable with a few tactile switches. 
+
+On the analog side, an AUX cable was hooked up from the breadboard to the function generator and a
+class-AB amplifier was added to the DAC for driving an 8ohm speaker. Finally, a .wav file of some
+dialogue was played, and the effect was successfully tested.

+
+I was pretty happy with my result, and surprised that I had a decent demonstration of digitizing
+sound with only three resistors and two capacitors.

 The main benefit of a CIC filter is its use in multirate systems as you can achieve large
 downsampling ratios with just adders and subtractors.
