WorldCup 2010 / VLC Vuvuzela Filter

Well, its not perfect, but its better than the original "sound":

VLC startup/cmdline parameters (windows: start -> execute -> cmd.exe, switch to your vlc directory and run the following line):

vlc --audio-filter param_eq --param-eq-f1=233 --param-eq-f2=466 --param-eq-f3=932 --param-eq-gain1=-20 --param-eq-gain2=-20 --param-eq-gain3=-20 --param-eq-lowf=100 --param-eq-lowgain=15 --param-eq-q1=10 --param-eq-q2=10 --param-eq-q3=10

Still missing one Frequency (1864hz) because VLC only supports 3 EQ parameters.

EDIT: Gets somehow better if you also lower 1ghz and 3ghz frequencies in the graphical 10-band equalizer.

With "real" software you can get much better results:
