以DSP为核心构建数字音频处理系统

Processing system of digital audio based on DSP

讨论了DSP的定点浮点格式、DSP的位数和DSP内部的算法对以DSP为核心的数字音频处理系统性能的影响 ,分析了自行研制的以DSP5 6 36 4为核心的吉他音效处理系统 ,该系统具有低廉的价格 ,较高的音频实时处理能力和CD级的高保真音质 .

The performance of processing system digital audio based on DSP is affected by DSP data type, DSP resolution and DSP algorithms. According to these factors, a guitar effects box based on DSP56364 is designed and developed. The effects box has lower price, higher real time performance and high fidelity audio.
