在matlab中读取多个wav文件 [英] read multiple wav files in matlab

问题描述

我想一对一地读取多个wav文件.我这样写，但是它给出了无效的Wave文件.原因:无法打开文件."错误.但是，当我将t更改为数字时，它可以工作.

I want read multiple wav files one by one in one folder. I wrote this way, but it gives "Invalid Wave File. Reason: Cannot open file." error. But when i change t to number, it works.

for t=1:10
    myFile=['path\','t.wav'];
    [ speech, fs] = wavread( myFile);
end

推荐答案

您需要将变量t转换为字符串.您正在要求打开文件'path\t.wav'，该文件可能不存在.由于变量t是整数，因此可以使用 int2str 将其转换为字符串:

You need to convert the variable t to a string. You were asking to open the file 'path\t.wav', which presumably doesn't exist. Since the variable t is an integer, you can use int2str to convert it to a string:

myFile = ['path\' int2str(t) '.wav'];

仅字符串可以与其他字符串串联.当然，如果文件少于10个，那么您将遇到另一个问题...

Only strings can be concatenated with other strings. Of course if you have fewer than 10 files, then you'll have another problem...
