A set of avisynth scripts that I use for my youtube videos.
The python script buildavs.py generates an avs file for to process the audio. MEGui available at https://sourceforge.net/projects/megui/ is a really great wrapper around avisynth.
In the scripts are some creative commans copyrighted files which are available on-line at.
