通过PHP在Linux上使用mp3进行wav

Question

I want your advice on how to convert mp3 files to wav on linux via a PHP script.

I was successful with lame but only on windows, I putted lame.exe and lame.xxx.dll together and executed the PHP script posted here:

But so far so good, I'm not successful in doing the same thing on Linux.

Answer 1

sorry, but afaik php is only gonna let you mess with id3 tags. you're gonna want to use an external tool to get this done.

use lame:

exec("lame –decode input.mp3 output.wav");

or use mpg123:

exec("mpg123 -w output.wav input.mp3");
