Xbox 360 Halo 4 - Spartan Ops!!!

[MLG L33T PRO]

Hey um I know I recorded this a while ago but I really want a solid response to the quality of the video. I know its not a HDPVR game-play but is it good enough maybe to do a walk through series of achievements or other tutorials? Is the audio quality okay, it sounds muffled and I used a pass through stereo to 3.5mm head set to record it to the PC using audacity any way to improve this with minimal cost, haha.

Any kind of feed back is appreciated!!!
