AudioProc monitors the combat log in real time and plays helpful audio cues when certain procs occur. I've chosen the procs that are interesting because when they happen, you have a small window of time to use a helpful, secondary skill or spell. This works with, augments the newly implemented Blizzard Power Auras.

Mage: Brain Freeze, Fingers of Frost, Hot Streak, Missile Barrage, Impact. Paladin: Ardent Defender, Art of War, Judgements of the Wise. Priest: Surge of Light. Warlock: Backlash, Decimate, Shadow Trance, Empowered Imp. Warrior: Blood Surge, Sudden Death, Sword and Board.
