This is a great series even if it's been like 2-3 years later. When it get really quiet and all of a sudden it gets loud my brother is like, "what the heck?!"
The audio has gotten wayyy beetter, it's just that the background noise can sometimes make it hard to understand what they are saying. Maybe adding subtitles would be a good way to go to get people stop bringing up the audio.
Hope you're still making videos in 2011 and I'm taking classes in digital arts and image and editing design, if you need any help you can just email me @ email@example.com
