Rough and ancient, but working version

When you try - the main thing is to edit these lines do not forget

$mp3 = new mp3('1.mp3');
$mp3->striptags();
// Second file
$second = new mp3("2.mp3");
$mp3->mergeBehind($second);
$mp3->striptags();
$mp3->output('word.mp3');

Answer 2

And opening an mp3 file as a binary one and slowly merging data from all files into one will not work?
