To say if a brain can do it, a machine can do it, is quit a degradation
of the very complex organ of human that can let us experience this
amazing world... Maybe you're sitting to much time behind your pc... ;)
@Sebastian:
I'm a guitarplayer and sometimes want to play a song of other
musicians... Sometimes its hard to hear for example the exact
guitarpart... Would be great if you can isolate that part and study
it... But maybe that is asking for a whole different way of recording in
a whole new filetype with a lot of Gb's....
