Vuvuzela Filter
Today I spoke with a colleague about the removal of the sound of those vuvuzelas during the world cup football broadcasts. It should not be that hard to build a vuvuzela filter, as the majority of the humming (that sounds like a swarm of bees from a distance) is tuned to B-flat. Of course, I was not the first one thinking of this.
Many TV-watchers complain, but who are we to ban this African tradition? Adding a filter should not be very difficult, and indeed it is not: the German Tobias Herre created a simple tutorial on how to set up a multi band equalizer in Logic Express to filter out the unwanted frequencies. Be sure to check out the included sound examples. The vuvuzelas are completely gone!

Hi there.
We (a friend and I) made a PureData version of the Vuvuzela filter:

yeah let's whitewash all football matches in all countries and make them all exactly the same. lol. i love the vuvuzela. it's part of the atmosphere. get over it.
There´s also a AU plugin for free. It´s not a simple notch-filter but uses sonicworx de-mix technology. Does a great job.

@Hans: I hadn't seen that one, nice. The download link didn't seem to work, so I changed it to the Vuvux home page.

I've been going to some matches, and boy I'm glad I brought ear plugs :-) It's actually quite incredible when you're there in the bee hive! And oddly enough one gets used to it. On TV it's really annoying though.
