Riddle me this. What sounds like an elephant when all alone, but sounds like a swarm of bees when numbers grow? The answer, as any World Cup aficionado will tell you, is the vuvuzela. A meter long plastic horn that has become synonymous with the 2011 World Cup in South Africa and has had many fans reaching for the mute button on their TV remote controls. The BBC has received so many complaints it is looking at ways to minimize the noise of the so-called instrument. Now researchers at the Centre for Digital Music (C4DM) at Queen Mary, University of London have come up with a "devuvuzelator" that filters out the droning sounds of vuvuzela for anyone watching the World Cup on a computer.
