     \begin{abstract}
         This report outlines the implementation, testing and evaluation of
         three real-time audio effects using the dsPIC 30F4013 digital signal
         processor.  Design choices, system specification, and final results
         are analysed.\\
-        Design choices are compared to choices made in previous work to outline
-        the changes required to implement such effects outside of
-        unlimited resource systems.\\
         System specification is compared with alternative chips to understand
         the quality of the processor in relation to the state of DSP
         technology.\\

         Final system performance is then discussed to determine further
         changes that could be made to improve performance.
