Trying to correct hyde park 76 audio

I feel kinda the same way. I mean the bad part of the audio will be clean and corrected which i really like but not sure if it's good idea to bring different source that has nothing to do with video feed especially with downgraded quality to it. I think i will leave this idea. Thanks for the feedback.

A Quad/surround mix with the audience in the rear would be interesting, would the recordings be difficult to sync ?
