摘要
设计了一种基于TMS320VC5402 DSP的数字音频效果器,可产生法兰、合唱、镶边、延时和厅堂的自然混响等各种效果。详细阐述了硬件系统的构成框图,分析了DSP多通道缓冲串行接口与外部AD、DA之间的音频数据接口设计及软件流程和典型音频效果的实现方案。实验证明在该系统平台上可很好地运行多种音频效果算法。
In this paper,a design based on DSP is proposed for digital audio effect generator, which can produce such effects as flanging,chorusing,delay and reverberation. The hardware design and digital audio interface between DSP and AD/DA are described in detail,and the audio signal processing flow chart and scheme of realizing certain audio effects are analyzed. Experiments show that various algorithms for digital audio effects can run well on this system platform.
