Digitally Filtering Out the Drone of the World Cup

qubezz writes "World Cup soccer fans may think a hornet's nest has infiltrated their TVs. However the buzz that is the background soundtrack of the South African-hosted games comes from tens of thousands of plastic horns called vuvuzelas, that are South Africa's version of ringing cowbells or throwing rats. It looks like the horns won't be banned anytime soon though. A savvy German hacker, 'Tube,' discovered that the horn sound can be effectively filtered out by applying a couple of digital notch filters to the audio at the frequencies the horn produces (another summary in English). Now it looks like even broadcasters like the the BBC and others are considering using such filters on their broadcasts."

    No, you're not. Not minding the sound is perfectly fine, but I've seen a lot of comments around the Internet insinuating that if you hate the sound of vuvuzelas, then you're a colonial racist who hates South African culture. As opposed to, say, someone who hates sounds that are really fucking annoying.

    Still, if the BBC and others are going to start filtering them, we get the best of both worlds. Nothing has to be banned, no ugly racial tensions are stirred, and we can watch the World Cup without being driven halfway to insanity. Count me pleased.

    Because it is something foreign, and probably also because it is African, they're all upset.

    Bull shit.

    People are upset because the noise is extremely distracting, conveys nothing about the fans' excitement with the game, and according to a South African audiologist who was on the news yesterday, the sound is well past the threshold for causing hearing damage.

    It would be one thing if the sound changed to reflect the excitement of the crowd during the game, but it doesn't. It's just a constant loud wall of sound at basically the same level from the start of the game to the end.

    It's similar in level and monotony to running jet engines at full throttle on test stands in the stadium, throughout the entire game. It doesn't add, it detracts.

    What you are saying is that traditions have to be respected, no matter how stupid or disruptive they are.

    I propose an alternative. All other countries should create a tradition of randomly setting explosive charges off in their stadiums whenever the South African team is there.

    It's our tradition, and you have to respect it.

    Except we don't. The players are unable to communicate on the pitch in any way, leading to the worst standard of play. As players cannot be warned when somebody is behind them, they just play safe and hoof the ball up the pitch just in case. The world's top players are being made to look like talentless hacks in dull low-scoring games. This may well go on to be the worst World Cup, and after this the Champions League finals may go on to eclipse the World Cup finals.

    DING DING DING! Sir, I'd like to let you know that you have won the Slashdot "Sperglord Post of the Year" award.

    Let's break this one down for all the viewers out there, John:

    "I have a better idea" - I am superior to everyone posting in this thread, particularly the parent.

    "Change the channel to something that isn't a sport at all" - I don't like games that are based on physical activity and skill. Sports are for dumb jocks who have no higher brain functions whatsoever. Now excuse my while I grab my 2-liter of Mountain Dew and Doritos and go raid Sunwell (or insert other WoW raid here, I'm not up on the current MMO trends)

    "Spectator sports are a complete waste of time." - I don't like sports, and therefore they are a waste of time. Never mind that my previous suggestion was to CHANGE THE CHANNEL TO SOMETHING ELSE, and that any television watching could easily be construed as a waste of time. You see, the fansubbed Anime imports I watch are not a waste of time, they are high art that is clearly superior to watching near physically superhuman athletes compete at the top of their game against some of the most skilled opponents they will ever face.

    So you see, sports are pointless and the only people who enjoy them are meatheads. Thank you, Grisnakh, for helping to perpetuate the stereotype that all Slashdot posters are scrawny, basement dwelling nerds that can't participate in activities that most well-adjusted human beings can enjoy.

    It's not a tradition it's a fad. These stupid things only began to be made and sold in south africa around 2001. That's not tradition. That's a fad. They never stop. It's not just during the game.. they NEVER stop. It's dangerous to be around them without hearing protection. They've been measured at 127dB. That's louder than a rock concert.

    And would I want to see a ban on fan traditions in my country? Um.. yeah. Yeah, that would be a good idea. FIFA really SHOULD start cracking down on fans acting like self-indulgent assholes and feeling entitled to act that way because, holy shit it's FOOTBALL and obnoxious hooliganism is part of the TRADITION dontchaknow.

    At what point should they step in? How about when fan behaviour actually starts HARMING OTHER FANS.. which these horns do.
    frankly I'd be overjoyed if this world cup turns out to have received abysmally poor viewership due to these things. Maybe then they'll act.

    I admire FIFA's decision, they valued the host nation's fans over the international fans.

    Let's not go pretending that this is some little guy sticking it to The Man kind of thing.

    I know that quaint ethnic traditions are pure and good and "homogenization" is evil, but when you hold an international sporting event, there's the expectation that the players should be able to play the goddamn sport without interference from the fans. It's up there with "providing a stadium", you're just kind of expected to do that.

    And yes, if the fan traditions of my country are disruptive to the game, I would very much like FIFA to ban them.

    The american viewership will be abysmal because the coverage is not even at the standard of american football 40 years ago. What they need is more angles, more cameras, flying cameras, cameras on players, gyroscopic camera in the ball, cameras on the fans, cameras on the refs, cameras on hot babes, cameras cameras cameras... and someone that is good at producing to throw it all together live, so the thing flows and isn't confusing.

    Sure, the way they shoot your football now it's like you're actually there... in the nose bleeds on one side if the field or the other. That shit is boring. I simply don't understand how there's all that money your football games, world cup... it's so much bigger than american football most Americans aren't aware... and they can't seem to understand that only Hollywood and it's decendants are any good at television, and in particular, sports coverage... I guess my point is, when you're that rich, you don't chince on the part that will make you richer... you buy the best, and instead, the foreign football games are produced by Mr. Magoo.

    Btw, not sure why they haven't been notching these frequencies out... I mean, I can't believe the first engineer (or any of the engineers since) at the first broadcast of these obnoxious and meaningless noisemakers didn't just dial them in and drop them out... seems like it'd almost be a reflex to do that, so I call WTF on inexperienced foreign broadcasters.

    You don't have to worry about the camera angles, the 0-0 games are MORE than enough to keep me from watching.

    Last night's (my time) Portugal vs Ivory Coast 0:0 game was one of the most exciting in this cup yet. Uruguay vs France 0:0 was tedious and as exciting as watching paint dry. The fact of being a scoreless draw is not determinative of the quality of the game.

    Now I can understand not watching a football code you don't personally enjoy. I don't watch AFL, Rugby only very rarely and for me American football makes even golf look exciting. What I certainly wouldn't do is bother to read articles about games I don't like, let alone comment on them.

    What's more, I figure, it's probably me, rather than those games themselves. After all millions of people get excited about the other codes. I guess that American football, for instance, requires an understanding of the strategy and tactics I simply don't possess. It might be a bit like a cross between chess and football for those who dig it. To me it's a series of erratic starts and stops, hardly any time is spent actually playing?! I get as much out of it as I would from a recital of Armenian poetry.

    OTHO, anyone who fails to appreciate the beauty of a game like the scoreless draw between Portugal and the Ivory Coast is clearly a deranged philistine! ;)

    The problem is not to get the Vuvuzela sound out, the real difficulty is to keep as much of the other sounds as possible.

    If you use your television's equalizer you will filter too much sound which in effect kills the atmospehre.

    Getting the right sound in while letting the annoying Vuvuzela out is some seriuous job in sound enigneering. But hey, everything one doesn't understand must be easy to do, right?
