Website/Program to extract instrumental from a song

Anyone knows such programs which i could use for taking out the lyrics and leavin just melody?

WOULD Begreat if they were free...
Sorry.couldnt find the right section

totally not the right section, however I can answer your question. No, never and impossible.

Once a recording is "baked" such as a live performance or recording from soundhound/spotify it is over. Only a multitrack original can retain this information. For a complex explanation please see acoustic wave theory.

I use wave editors day in and day out. This feature however is never going to happen, which is why you always keep the src recordings no matter what forever
