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 this would be great. If it is written in Python it would also be ok.
Here is an example: http://www.youtube.com/watch?v=TIViQuCX7XM#t=5m4s
No, this isn’t possible. The sound of applause covers a very wide band. Filtering vuvuzelas was somewhat possible because they were all close to the same pitch. Applause is all over.
If you want to experiment, pull up this video and play with your EQ in VLC. Even with the wide bands of a 7-band EQ, you’ll be dropping quite a few to cut the audience, thus leaving you with nothing.
