[jitter] Video and audio?

I don't know what forum to put this under.  I am kinda new to Max MSP \ Jitter.  I am trying to get into video scrubbing.  I was wondering if there is an easy way to control treble, and bass levels coming out of a jit.qt object that is play an .mp4, also lets say there is music being played by two jit.qt's how would someone go about creating a beat matcher for the audio outputs.
