How to Filter the Vuvuzela on your TV
The vuvuzela has created quite a stir during the FIFA 2010 Football World Cup. Some people love them and some people hate them. British bookmaker William Hill is now taking bets on whether the horns will be banned at Premier League stadiums next season. It's caused so many complaints that the BBC is trying to figure out if they can filter out the sound from their broadcasts.
A company called Audionamix is already providing vuvuzela filtering to French pay television broadcaster Current+ and Host Broadcast Services, the company that provides the broadcast feed for the World Cup, says it has doubled its audio filters to reduce the drone of the plastic horn.
Filter it out yourself
If you spend some time on Google you can find complicated ways of filtering out the vuvuzela sound, but here's a quick and easy fix.
If you have a modern television you can customise the sound settings in the Equalizer. The guys over at Lifehacker.com had some success by dropping the EQ at 465Hz and 235Hz. "Ideally you'll reduce each frequency by at least 40dB (which got rid of the drone completely for us)" they say.
For those of you who know how to drive audio through a component graphic equalizer, then perhaps you'll know how to use this information more effectively. Apparently, the vuvuzela drones at 233Hz, with harmonic overtones at 466Hz, 932Hz, and 1864Hz
There's another guy over at BookofJoe.com who says he managed to reduce the sound by adjusting his sound settings as illustrated in the pic below. You reduce the 300hz range and boost the adjacent EQs.
Own a Mac? Free anti-Vuvuzela plugin
I haven't tested this, but apparently it works brilliantly. Head on over to vuvux.com for a free plugin that can easily filter out the vuvuzela drone. But the best part is that "The process used in VuvuX has been developed to distinguish between voice, Vuvuzela hum and background noise by applying pattern detection and tracking." This gives you the full sound and just kills the vuvuzela. Nice one!
