基于Matlab GUI的参数均衡器设计

Design of Parametric Equalizer Based on Matlab GUI

参数均衡器是一种音频处理设备,是音效管理器不可或缺的组成部分。本文首先给出了一种实现参数均衡器的新型算法,然后采用Matlab GUI设计了该参数均衡器,该参数均衡器能够便捷的随时修改中心频率、增益、品质因数等参数,并能实时地对音频信号进行参数均衡和音效处理。最后对该参数均衡器进行了性能测试与分析。结果表明,该参数均衡器具有参数易于调节、滤波效果好等优点,并能很好的改善音质。

Parametric Equalizer（for short as PEQ）is a kind of audio processing equipment, especially the indispensable part of the sound management. The paper first made a introduction to a new type of the PEQ realization algorithm. And then a design and realization of PEQ based on Matlab GUI was proposed in detail. The user can intuitively operate the PEQ and process the signals. At last the PEQ performance was tested and analyzed. The result demonstrated that the PEQ had several advantages, e.g. parameter was easy to be adjusted, filtering effect was good, and so on.
