Need help with music editing
 

Hi, I was wondering if anyone could tell me how exactly I could extract JUST the music from an mp3 or wav file. I mean, leave the sound effects and the voice. I know there are vocal removers out there, but there are no sound effects removers. Here is an example of someone who has managed to do this, but he/she refuses to tell anyone how it's done: ww w.youtube.co m/user/mi7gtaf (without the spaces obviously)

If anyone could tell me of any software or something I could use to achieve the same results as him, please can you tell me. Thanks.
