The blog Surfpoeten has released instructions how to filter out the annoying sound of the Vuvuzelas at the 2010 World Cup games with the help of a ‘high-slope band stop filter’ and a computer. However, many of us do not to have the software Apple Logic Express 8 (or other versions), which is required to be able to follow the instructions of the Surfpoeten.
In principle, the construction of the filter is quite simple. The audio signal must be transmitted from the receiver to the PC, where you can apply frequency-specific filters in realtime. Therefore, we have searched for other options and found some that work for PC users as well.
On the blog icanmakeit.de, the author presents an effects preset for Ableton Live software that allows you to configure the multi-band EQ of the software so that the Vuvuzela sound disappears from the soundtrack or at least get well-damped.
Next, you can download on icanmakeit.de a Vuvuzela filter for energyXT and use it immediately. But those who do not possess the program and don’t want to buy it, can build their personal Vuvuzela filter with a VST hos, and an equalizer plugin. This is also described on this blog with a nice manual.
With a little effort, you can adapt the filters to other programs such as WinAmp, Audacity and Adobe Audition. Another idea would be to filter a live broadcast via Internet radio stream directly on the PC and then listen to the radio stream instead of the TV soundtrack.
So we wish you success your personal recording studio work and to enjoy a more silent great 2010 World Cup.
