Prosoniq recently released the world's first real-time Vuvuzela filtering plug in based on sonicWORX' audio de-mixing technology.
VuvuX is a free AudioUnit plug in that suppresses the noise created by the South African trumpet called "Vuvuzela" in realtime without affecting the audio commentary or the stadium atmosphere, allowing you to enjoy a noise-free World Cup 2010. Version 1.6 is the latest version.
VuvuX Developer SDK available for Mac OS X, Windows and Linux
Prosoniq has also released a developer SDK for the demixing-based Vuvuzela filtering technology to the developer community. The SDK contains example projects that build and run right out of the box on Windows, Linux and Mac OS X. The SDK comes with an evaluation library of VuvuX that allows 30 minutes of uninterrupted processing of audio streams. A commercial version of the library is available for licensing.
