Compact Flash Player Cyclone Edition
====================================

This design reads raw audio data from the compact flash card inserted in the Cyclone Nios board compact flash socket 
and uses delta-sigma convertion to output the audio stream through the Lancelot audio port.  

Copy the music.raw to the compact flash card. The utility Memory card explorer is a tool to write the raw audio data to the compact flash card.
