语音增强 logmmse matlab算法
function logmmse(filename,outfile)
%简单来说,这里对噪声谱估计两个步骤
%1、前6帧都当噪声计算,计算出初始噪声功率谱
%2、加上粗略的vad判决更新噪声谱
%后面就是MMSE-LSA也是LogMMSE的计算勒
% Implements the logMMSE algorithm [1].
%
% Usage: logmmse(noisyFile, outputFile)
%
% infile - noisy speech file in .wav format
% outputFile - enhanced output file in .wav format
%
%
% Example call: logmmse('sp04_babble_sn10.wav','out_log.wav');
