If you’ve wondered what that annoying constant background drone is while watching World Cup matches on TV, its a type of plastic horn called Vuvuzela, and its been irritating spectators to no end at this year’s event. The horn is blown by World Cup fans to celebrate such moments in a game as — well, every moment — and has achieved unprecedented fame and rancor this Cup, as its B-flat drone is broadcast around the world. Long after the games have ended and the TVs have been shut off, the Vuvuzelas continue to echo in our ears.
From German blog Surfpoeten comes a DIY solution for home Cup-watchers driven to distraction by the stadium horns: a software filter that selectively mutes the particular frequency of the vuvuzela. The horn drones, apparently, at 233 Hz, with harmonic overtones at 466 Hz, 932 Hz, and 1864 Hz.
Tube, the inventor behind Surfpoeten, runs the audio from his TV through a Mac Mini running Logic Express. A series of bandpass EQ filters in the software neatly excise the offensive frequencies, leaving the game blissfully vuvuzela-free.
Tube isn’t the only one with that idea — I noticed at least one pub in New York yesterday doing the same with a component graphic equalizer hooked to a giant TV. For those of you following at home, that’s 233, 466, 932, 1864.
In-person spectators at the games still have little recourse. Perhaps in 2022, when we all attend holographic games at our home stadia, EQ filters will be built in.
