Update (18:08): more filtering! (see below)

Since some people (PCWelt, VLC Team at Facebook, ...) are actually interested ín vuvuzela-blocking-stragegies (Seems like they just copied the startup parameters *shrug*),
here is the next level of vuvuzela-filtering: (The easy solution is for Windows-Users only this time - feel free to compile a Linux binary, Sourcecode included).

I modified the VLC param_eq Plugin to take 4 instead of 3 parameters and included the vuvuzela-frequencies as default-parameters.

Feel free to include a link to this page this time

If you have any ideas to improve this filter (e.g. better frequencies, ...) - please leave a comment

So all you have to do is:

(0. Get VLC 1.0.6 - should also work with 1.0.5 (and maybe some other versions))
1. Download Zip File
2. Extract the libvuvuzela_plugin.dll to your $VLC\plugins directory
3. Enable the "Vuvuzela Filter" (Advanced Audio Options -> Filter) (Running VLC with "vlc --audio-filter vuvuzela" parameter should also work)
4. Restart VLC
5. Enjoy.

This time i created some audio samples:

Without any filtering:


Filtered:


(Yes, this is OGG Vorbis Playback in HTML5, if it doesn't work for you: get a real browser! (Chrome / Firefox)

UPDATE

Fixed copy&paste Bug (updated v1.0)

UPDATE / Experimental
Added 2 additional frequencies from https://www.audiocation.de/blog/2010/06/15/vuvuzela-filter/ (could be too much, doesn't sound that good anymore... )

Filtered (Version 1.1):


Files:

Download VLC Version 1.06 Plugin .dll - Win32

Sourcecode vuvuzela_1.0.c (Fixed copy&paste bug)
Sourcecode vuvuzela_1.0.c.txt

For incompatible browsers that can't handle HTML5 audio:

Download demofile - without filtering
Download demofile - filtered (1.0)
Download demofile - filtered (1.1)

Experimental Download VLC Version 1.06 Plugin .dll - Win32 - Version 1.1 (2 more Frequencies)
Sourcecode vuvuzela_1.1.c
Sourcecode vuvuzela_1.1.c.txt

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:
