摘要：
Audio effects processing technology is widely used in various types of music production, live performances and other occasions. Most of traditional technologies produce real-time audio effects with hardware analog circuits. In this paper, focus on the demand of time scaling, pitch shifting and special effects of real-time audio. Improve the algorithm performance, efficiency and effectiveness in subjective base on traditional phase vocoder [1] model in high performance DSP processor BlackFin which be made the use of its structural features. Experiment shows that, new algorithm do well in both computation and hearing effect.
