to celebrate the come back home of the French team, I’d like to share with you the easiest way to cut the annoying buzzing of vuvuzela in Ubuntu (compatible with all Gnome system).1- Download and install PulseAudio Multiband EQ
- download here:
- install the needed package (in a terminal):
sudo apt-get install ladspa-sdk
- install PulseAudio Multiband EQ:
sudo dpkg -i pulseaudio-equalizer_2.7_all.deb
2- Create the filter by copying the following lines in to the new file ~/.pulse/presets/vuvu-cut.preset
- create the folders:
- the 4 frequencies to mute: 233Hz, 466Hz, 932Hz and 1864Hz (thanks surfpoeten.de).
- save the file and exit:
Ctrl+O and Ctrl+X
- prevent the changes of the presets file by changing the right:
chmod 444 ~/.pulse/presets/vuvu-cut.preset
3- Now, when you want to watch a match
- open the soft in the gnome menu Applications/Sound & Video/PulseAudio Equalizer
- select EQ Enabled and choose the vuvu-cut in the Preset list.
Enjoy the rest of the World Cup 2010 without the French team (I have to confess now, I’m a bit sad for my country).Sources:
