They are the vocal and<br>instrumental versions of a classic 80s pop song. I'm fiddling<br>about with my own remix, and I'd love to do the 'subtract one for<br>the other to get an acapella' trick. This usually works really<br>well on digital files, especially when the mixes are otherwise<br>identical as these are. The problem with these ones is that they<br>are not quite digitally identical, but have each been through an<br>analogue tape stage, which has introduced a *tiny* bit of speed<br>instability, inaudible, but enough to make digital subtraction a<br>nightmare as the files drift away from each other by up to about<br>50 samples per bar. I can match up .2 to .5 second bits perfectly<br>and get a tiny snippet of crystal clear acapella, but what I<br>really need is a way of either automatically phase-locking the<br>files, making almost imperceptible pitch bends, or automating<br>very very short delay changes.<br><br>Logic Pro is frustratingly hopeless at this, it provides a sample<br>accurate delay plug in, with sample accurate automation on the<br>delay times... but the automation can only be set in massive<br>clunky increments, and I can't find any way at all to adjust it<br>precisely.<br><br>Any ideas, folks?<br><br>- Andy_R<o:p></o:p></p></blockquote><p class=MsoNormal><o:p> </o:p></p></div></div><p class=MsoNormal>Hm, I think Ableton Live will be able to do this quite well.
