Vuvuzela Filter

EyeTV 3.4 Special Edition
For a limited time only

A special edition of EyeTV 3.4 software is available during the 2010
FIFA World Cup that offers a new feature called the “Vuvuzela Filter”.
This filter gives you the option to dampen the buzz of vuvuzela horns
in the stadium during live TV broadcasts; it can be quickly switched
on and off at any time during the game. To use the filter, control
click to bring up the contextual menu in EyeTV.

Click here for a quick demonstration of the Vuvuzela Filter in action.

They need to add a second bandpass filter to kill the harmonics. The video only gets rid of the lower frequencies (to my ears).

From the internets 😉

Use the EQ as a bandpass filter to get rid of the annoying frequency around 233 Hz and the corresponding harmonics (466Hz, 932Hz, and 1864 Hz)
