如何使用文件夹读取和写入多个Wav文件 [英] How Can I Read And Write Multiple Wav File Using Folder

问题描述

for i=1:5
    for j=1:5
        fnsil=fprintf('sad%d%d.wav'i,j);
        fid=fopen(fnsil,'r');
        fr=fscanf(fid,'%f',1);
        fclose(fid)
        for a=1;fr
            kk=fscanf(fid,'%f',1);
            ex(i)=kk
        end;
    end;
end

推荐答案

我不知道Matlab但是我很确定从封闭文件描述符读取会失败那里也是。还有一些缺少分号，一个循环范围包含冒号而不是分号。所以你可以试试这个：

I don't know Matlab but I'm quite sure that reading from a closed file descriptor will fail there too. There are also some missing semicolons and one loop range contains a colon rather a semicolon. So you may try this:

for i=1:5
    for j=1:5
        fnsil=fprintf('sad%d%d.wav'i,j);
        fid=fopen(fnsil,'r');
        fr=fscanf(fid,'%f',1);
        for a=1:fr % Replaced ; by :
            kk=fscanf(fid,'%f',1);
            ex(i)=kk; % Added missing semicolon here
        end % Removed unnecessary semicolon
        fclose(fid); % Moved to here and added missing semicolon
    end % Removed unnecessary semicolon
end
