Howto: Filter out vuvuzela noise on your PC

tronator

Hi everybody,

I came across the following instruction how to filter out the annoying vuvuzela noise on your computer.

http://www.afterdawn.com/news/article.cfm/2010/06/14/vuvuzela_buzz_ruining_your_world_cup_get_rid_of_it

It describes it for Windows, Mac and Fedora. For Ubuntu I found this thread

In short, if you use mplayer, start it with these options

mplayer -af pan=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

Or you could use the pulseaudio equalizer

sudo add-apt-repository ppa:psyke83/ppa
sudo apt-get update
sudo apt-get install pulseaudio-equalizer

and copy and paste this in ~/.pulse/presets/vuvuzela.preset

Then open the PulseAudio Equalizer and select the vuvuzela preset, enable and apply.

Still not ideal, but at least you can hear the chants from the crowd.

For MythTV there is a patch available, but it will not find it's way into the repos. I will try this one later...

Happy watching ;-)

Also, I heard that BBC was planning to offer a Red Button service that shows the matches with the noise removed.

Hmm maybe they were only 'thinking about' the idea:
