摘　　要：介绍了一种基于DSP的电吉他音效器音频系统的总体方案和硬软件设计,着重说明如何利用TMS320VC5409内部多通道缓冲同步串口(MCBSP)和A/D以及D/A的硬件连接来实现音频信号的采集及输出,并对回声音效算法进行软件设计。实验表明,该系统明显改变了电吉他的音色,具有很强的推广价值。This paper presents an ensemble scheme and some hard/soft wares design about an audio effect processor 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.
