| Abstract: | This paper presents an ensemble scheme and some hard/soft wares design about an audio effect proces- sor for electric Guitar based on TMS320VC5409,stressing on how to use the internal multi- channel buffer serial port (MCBSP) of TMS320VC5409 and the hardware connections of A/D and D/A for the realization of audio signal acquisition and output. An algorithm for the sound effect of echo is designed with software. Experiments show that this system improves the timber of electric Guitar,and has a higher value for its application. |
