摘要
谱减法是处理宽带噪声较为传统和有效的方法,它的运算量较小,容易实时实现,增强效果也较好。比较详细地叙述了谱减法的基本原理和降低音乐噪声的方法。
The spectral subtraction method is a traditional and effective method to deal with wideband noise. Its computation is small, real-time implementation is easy and the enhancement effect is very well. This paper described the basic principle of spectral subtraction method and the methods of decreasing music noise in detail.
