程序功能:

1.读入wav下的所有音频

2.每个音频截取前0.6秒

3.合并每个音频

 

clear all;cd = 'wav';waveFiles = dir(fullfile(cd,'*.wav'));len = size(waveFiles,1);Z = [];for i = 1:len    fileName = [cd '/' waveFiles(i).name];    disp(fileName);    [X, fs] = audioread(fileName);    X=X( ( 1 : int32(fs*0.6) ), : );        Z = [Z; X];endfor i = 1:len    fileName = [cd '/' waveFiles(len - i + 1).name];    disp(fileName);    [X, fs] = audioread(fileName);    X=X( ( 1 : int32(fs*0.6) ), : );     Z = [Z; X];endaudiowrite('final.wav',Z,fs);
