Why is the audio speed so weird?

Over here one of my viewers asked “Why is the audio speed so weird?” The answer is that I was speeding up the video in an attempt to make the content more “lively” and so viewers could get through 6 minutes worth of content in only 4 minutes. However I have come to understand that others don’t think this is a good idea, so I have canceled the various videos I had queued for release, and I will remake them without the speed ups. I won’t be redoing any of the videos I have already released though, so that history will stand. :)
