摘要
设计了以ARM S3C44B0X为核心处理器的数字音效处理系统,研究了数字失真类音效算法的建模和实现。从硬件设计方面着手进行了具体系统设计,对Amplify音效,介绍了基于自适应滤波器系统辨识方法建立线性失真音效数学模型的方法。在软件设计中,介绍了音频信号延时、混响、压缩、均衡、失真等效果的设计处理。
Using RAM S3C44B0X as the central part of the processor, an audio effects processing system is proposed. The hardware design is compared and analyzed, and the model of amplifies effect is taken as an example for modeling of linear distortion effects using adaptive filter. The software designs to implement delay, reverb, compressor, equalizer, and distortion effects are introduced.
