description
This paper describes the development, design, andimplementation of a simple, multi-channel, audio effects processor.Simplicity of design is emphasized, and achieved by using asingle TM320C6713B digital signal processor (DSP).The DSP manages both user interface, and audio processingfunctions. Therefore, this design avoids the high complexity,component count, and cost that is typical of designs using microcontrollersas system hosts. A block diagram of the single-DSP system, and descriptions for each of it’s main hardware components are given.Six audio effects are implemented on the system. A blockdiagram and description for each is given. In addition, C-codeis given to implement four of the audio effects.
