As a pseudo-audiophile I find myself very interested in the latest buzz around Direct Note Access, the new technology behind Celemony's "Melodyne" audio processing software. Akin to current Auto-Tune processing (which can correct a single pitch), Direct Note Access gives an audio engineer the ability to identify and manipulate individual notes from within pre-recorded, polyphonic material. For example, one could change specific notes in a guitar chord or even fix one wrong note played by a musician in a symphony orchestra.

If you have a few minutes, watch the demo video featuring some of the software's core capabilities. It's pretty fantastic stuff from an audio engineering standpoint, but I realize this isn't the kind of thing that everyone can get excited about. I'll post again when they come up with software that makes Nickelback sound good.
