The 1.0 version of VuvuzelaFilter for Mac was available to download on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free software for Mac OS X was originally produced by Albert Feller. We recommend checking the downloaded files with any free antivirus.
From the developer:
VuvuzelaFilter helps you enjoy the football games without the noise of vuvuzelas. With a loudness of up to 120 db(A) and thousands of them used during the world cup games, they sound like a a swarm of monster wasps. It does not only make it nearly impossible for the soccer players to communicate acoustically on the playing field but does also annoy many fans who want to enjoy the world cup all over the world through television.
