Matlab之合并音频

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];
end

for 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];
end

audiowrite('final.wav',Z,fs);
