| Abstract: | 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. |
