The when you ‘dim’ vocals in a mastered audio file what you’re actually doing is assuming that the lead vocal is panned dead center and the other instruments are panned stereo left and right. When you take one side of the file, and reverse the phase (flip the wave file so that it’s upside down) the vocals, being down the middle, will cancel each other out. This is fairly ineffective most of the time, and won’t work at all if the vocals aren’t central in the mix. Also, if there are other instruments down the center, commonly bass etc. they will be affected too.
There is no way to achieve the opposite affect and ‘dim’ the instruments, the mechanics don’t work.

Seems like a lot of hassle for little gain, and deleting frequencies had the same effect as filtering them as the end result is still their absence from the mix + why , why on god’s good earth would you edit a wave file in photoshop?
I can’t even begin to describe how wrong that concept makes me feel inside.
Any examples of tracks you’ve done in this manner? I’m desperately curious…

In a real recording studio, the usual practice for many years has been to record all the instruments as separate, individual tracks so that you can alter the volume of each separate thing, i.e. if you want the bass louder you can turn it up because it a separate file. When this goes on cd, the song is ‘mixed down’ into a stereo file and all the tracks are no longer separate, however the original files remain unchanged. In order to isolate any element of a track, be it vocals or guitar or bass, it is these original files that you need to refer to, and from them you can get any little bit of a song without the rest of it.
For a little better understanding of the whole processof mixing and remixing, you might want to have a look at these vids :)

Notice how on the screen all the different instruments are individual files. You can ‘solo’ these to hear only one of them, make them louder or remove them from the mix completely.
Hope this helps a little, but there’s only so much I can explain to you in writing. If you’re really interested, get a copy of Logic 8 or some other easy to use recording software and play around with it until you get to understand it better.
