Description: 基于Wiener滤波的语音消噪Matlab源程序
调用方式：
output=WienerScalart96(signal,fs,IS)
signal－－输入含噪语音
fs－－－－语音信号采样率
IS－－－－起始静音端，用来估计噪声方差（秒做单位，默认是0.25秒） -Wiener filter-based de-noising of the voice call Matlab source code the way: output = WienerScalart96 (signal, fs, IS) signal- voice input with noise fs---- voice signal sampling rate IS---- Start mute end used to estimate the noise variance (units of seconds to do, the default is 0.25 seconds) Platform: |

Description: [Digital Signal Processing]
Digital signal processing (DSP) refers to anything that can be done to a signal using code on a computer or DSP chip. To reduce certain
sinusoidal frequency components in a signal in amplitude, digital filtering is done. The book examines the effects of sampling on signals and DSP systems. All DSP input signals are sampled, usually at equal intervals of time, in order to input numbers representative of the signal into a computer or DSP chip. Platform: |
