Windows only: Devuvuzelator is a portable and lightweight sound filter that reduces those droning vuvuzelas sounds easily from online World Cup videos and broadcasts, without any type of installation or messy EQ tinkering
The program applies a simple filter to the annoying sound played during online soccer matches across your system. The filter is adjustable in strength, you can enable or disable it with the tick of a checkbox, and it doesn't require you to fiddle with EQ filters, or to install this vuvuzela filter, which requires additional software.
In our tests, we found that the sounds were significantly reduced. Using Devuvuzelator on Medium strength barely filtered the vuvuzela horns from our video, but there was a substantial difference with the Strong and Very Strong settings—you can adjust to your preferences.
