World Cup 2010: howto turn off the vuvuzela on your TV

Hey folks,
all the funny solutions that have already been posted sound ok to me, but most people don´t have any equalization possibilities on their TVs, as well as most of you probably don´t have any professional EQing gear to hook up with your TV. So here´s a qood workaround that should do the trick: all you need is a laptop with stereo in and out (Windows or Mac), 2 x MiniJack <> RCA Cables, a stereo sound system or any kind of active speakers and a TV with either mono or stereo out (these white and red RCA plugs).
Just do the following:

1. Hook up your Laptop to the TV via the first cable: TV out goes into Laptop IN
2. Connect the Laptop OUT with the second cable to your stereo system (note: if you just have mono out on your TV just use either the red or the white plug) Choose “AUX IN” if you´re not sure.
3. Download and install Ableton Live intro as a demo version. It runs without serial legally for 30 days, so just fine for the WC 2010. Get it here: http://www.ableton.com/de/downloads
4. Run Ableton Live Intro. For the first time you need to select your computers sound device in the preferences, and make sure that IN and OUT stereo is active. Use the given “track 1” to select your 1/2 channels and set Monitor to IN, and turn up the volume. You should see the meter lights indicating your TV sound.
5. Check if there is any sound coming out of your stereo on the input that you connected your laptop to. Turn up the volume of your laptop until it suits your needs. You should hear the TV sound now on your stereo. Check if your TV does still output sound on the internal speakers. Normally it should not when externally connected – if yes, turn it down so it will only come out of your stereo system (maybe you need to adjust that in your TV settings)
6. Go to the master channel in Ableton Live Intro: drap´n´drop the spectrum analyzer and the 8-band EQ from the left menu in Ableton Live to the Master Channel. If you´re not sure what I am talking about, look for the “Audio Effects” tree in the second tab on the left, and try dragging things into Ableton. It´s easy 🙂
7. Use the spectrum analyzer to find out what frequency the vuvuzela sound has – normally it should be somewhere around 300 Hz. Use the 8 band EQ to turn down the 300 Hz band, play around with the parameters until you don´t hear any vuvuzela anymore, but still hear the screaming and the comments of the game. Here you go! Now you have your own little Anti-Vuvuzela-Solution, without any license or anything else – you just have to set this up again every time you start Ableton, so maybe just leave it open the whole day 🙂
8. If you want you could even add the Ableton “Multiband Compression Effect” and turn up the heights until it fits your needs! Enjoy the games without the vuvuzela sound.

Cheers!
