Does audio affect the video codec?

The data rates for the various quality stages seem to state effects on video, but isn't audio also encoded within these rates? If one were to simply mute the audio inputs on the HMC150, would it visibly improve the codec?

Additionally, is there anyone who uses the 'flat' 1st scene file? As in, no in-camera modifications, just the raw untampered image?

Delving more deeply in AVC I am now trying to figure out how I can maximize my camera, and if the audio is encoded alongside the video is a lossy AVC container, it seems like the audio not existing would leave more space for the video codec.

I'm sure I'm wrong about this so please fill me in. I'm a student in your classroom on this one.
 
The space that the audio codec uses is not determined by the audio volume. Turning down the volume will do nothing and, as far as I know, there's no way to eliminate the audio track from being recorded.

I usually use scene file 1 but have recently started messing around with settings in an effort to reduce noise.
 
I looked it up further and it seems that AVCHD records 21mbps of video data and 3mbps audio and "other data".
