I would like to edit the audio that is in the videos taken on a Pentax S50 digital camera at a concert recently. The sound is horrifically distorted and is barely audible. I have used AOA Audio extractor to extract the audio but im lost as to how to remove the distortion. i have tried ulead videostudio, adobe premiere, sony vegas and im getting nowhere. I have also Audacity and audio edit deluxe. the problem is that most of these are trial versions and will soon run out. my biggest problem is im not sure exactly what part of the audio im supposed to try and edit. I would really appreciate any help that anyone could give me on this problem. Thanks in advance.
