The merger of two mp3 players

Question

Do you know a class to merge two MP3 files using PHP?

I did not find anything on Google.

Answer 1

If by merging you mean placing one sound over another, then please do not pay any answer to it.

If you do not want to transcode MP3s, you can simply add them. I know this worked for MPEG movies, so I think it can work for MP3s too. Another option is to add audio files to the Zip archive without compression, and then rename the extension to .mp3.

I did a quick test and this

file_put_contents('combined.mp3',
    file_get_contents('file1.mp3') .
    file_get_contents('file2.mp3'));

. ID3 , . . .
