This question already has an answer here:
I need to put an MP3 file over another one in a specific time slice of whole file.
Is it possible to do this? If so, is there any library or method?
I dont want to put them one after another. Such as;
file_put_contents('combined.mp3',
file_get_contents('file1.mp3') .
file_get_contents('file2.mp3'));
</div>
