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!
