If you are a fan of the World Cup series, but can't stand the constant annoying sounds of the vuvuzela then check out the latest free application from Stardock in collaboration with the Centre for Digital Music at Queen Mary, University of London.

No installation required, just download and run on Windows. The application filters out the noise of the Vuvuzela on streams from the BBC and ESPN etc.
