MyRIO FPGA Audio Pitch Changer

Title: MyRIO FPGA Audio Pitch Changer

Overview of what project is:
Changes the pitch of an audio signal passing through the MyRIO audio input and output ports. For example, you can connect the "Audio In" port to your MP3 player and the "Audio Out" port to your headphones, and listen to your favorite songs at a higher or lower pitch. The pitch-shifting algorithm was developed under guidance from this site.
