This football Worldcup in South Africa is notorious for two things until now. Boring football games and the annoying sound of the vuvuzela, the blaring horn that drowns all other background noises out.
Some football watchers helped themselves by turning off the sound of the TV while others played around with their TV’s equalizer to reduce the impact of the vuvuzela on the overall sound.
The developers of VLC Media Player have now posted instructions on how to reduce the sound of the vuvuzelas while watching soccer.
This does however mean that only users who watch football in VLC will be able to enjoy the games without those sounds.
This basically means that users who use a TV card in their PC can benefit from the startup parameters, as do users who watch recorded games on their PCs.
VLC Media Player needs to be started from the command line with the following parameters to remove the vuvuzela when watching the world cup.
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
The parameters can be added to a batch file that needs to be placed in the VLC directory so that the commands are executed without having to issue them on every startup.
Just download this batch file and extract it into your VLC directory. Execute it whenever you want to watch football.
A similar option is available for Mplayer users, they need to issue the command
mplayer -af an=1:0.5:0.5,sinesuppress=233:0.01,sinesuppress=466:0.01,
sinesuppress=932:0.01,sinesuppress=1864:0.01,sinesuppress=232:0.01,sinesuppress=465:0.01,sinesuppress=931:0.01,sinesuppress=1863:0.01,sinesuppress=234:0.01,sinesuppress=467:0.01, sinesuppress=933:0.01,sinesuppress=1865:0.01 name-of-video
This command can be added to a batch file as well. It does however require the video file name as a parameter which means that it needs to be edited whenever the video changes.

Glad to see so many people working on this problem. Those horns are atrocious! The Lifehacker solution using a stereo equalizer to fix live broadcasts is also very interesting.
