Digitally Filtering Out the Drone of the World Cup
qubezz writes "World Cup soccer fans may think a hornet's nest has infiltrated their TVs. However the buzz that is the background soundtrack of the South African-hosted games comes from tens of thousands of plastic horns called vuvuzelas, that are South Africa's version of ringing cowbells or throwing rats. It looks like the horns won't be banned anytime soon though. A savvy German hacker, 'Tube,' discovered that the horn sound can be effectively filtered out by applying a couple of digital notch filters to the audio at the frequencies the horn produces (another summary in English). Now it looks like even broadcasters like the the BBC and others are considering using such filters on their broadcasts."
My TV already has a digital filter. Its called the off switch.
1. Cricket bat.
2. Hearing Aid.
3. Petrol funnel.
4. Water sprayer. (force trumpet side down into water)
5. Drinking funnel. Nuff said.
6. 4G mobile communication
7. Walking stick,
8. Light saber. (Just insert a torch) as seen on Starwars...
9. Jousting Stick (simply insert one into another.)
10. And of coarse... supporting any team/thing you like...
there is no spoon. or fork. there is a butter knife, and it's dull.
The human brain is actually pretty good at filtering out noise if you give it a chance.
Well, that and progressive hearing loss.

Chatroulette and sports broadcasters all trying to filter out the horn on the same day?
What?

Since that is not a part of our culture, may I suggest an alternative that is a well established part of our (geek) culture: pointing laser pointers at things. Imagine if every geek in the audience pointed one of the WickedLaser 1W blue lasers at the opposing goalie....

Call me when it works on Glenn Beck or Rush Limbaugh.
If brevity is the soul of wit, then how does one explain Twitter?
I would say woosh but you probably won't be able to hear it over the vuvuzelas...
A guy on holiday in Spain, feels somewhat hungry, so goes into the village restaurant. Gets the menu and after some careful study, orders the paella. Quite tasty it was too, but there was an absolutely delicious smell coming from the next table, where one of the locals, Carlos, was eating.
He calls over the waiter, and in his best holiday Spanish asks: "Tell me, what is that dish there, the one that smells so fantastic."
The Waiter replies: Ah yes, that is made from certain rather delicate areas of prime freshly killed bull. It is then marinated in our secret sauce mix, and garnished with fresh herbs, and just a touch of garlic, with our special red wine dribbling.
"Sounds superb, may I have some please.?"
"For you sir, as a special favour. But we have none left today. Come back tomorrow, an hour or so after the bullfight finishes"
The guy arrives on cue, his meal is ready, piping hot and tastes out of this world.
He calls the waiter over again, tips him hugely, sends his compliments to the chef, but asks. "But tell me, why was my portion so much smaller than the one Carlos had yesterday"?"
The waiter shrugged and replied "Senor, sometimes the bull wins...".
