I asked this question before on stackoverflow ( http://stackoverflow.com/questions/5299338/filter-applause-from-videos ) and got the hint to ask it here:
I am currently watching a video from 27C3 and I would like to filter the applause, as it is very loud. Is this possible? I have heard something like this was made for Vuvuzelas.
I use Ubuntu. If this filter would work via ffmpeg / Audacity this would be great. If it is written in Python it would also be ok. I know the normalization with the VLC-Player, but thats not a very good solution
Here is an example: http://www.youtube.com/watch?v=TIViQuCX7XM#t=5m4s
