Prosoniq introduces free vuvuzela filtering plug-in

Submitted by on June 30, 2010 – 2:19 pm 2 Comments

If you’ve seen any of the World Cup soccer matches, or watched the news on TV, or even if you’ve been awake at all in the last few weeks, you know all about the plastic vuvuzelas that fans use to make noise at these matches.

Well, Prosoniq has taken it upon themselves to help us all deal with this annoying sound. They have created VuvuX, a free AU format plug-in that uses Prosoniq’s Sonicworx audio de-mixing technology to eliminate the sound of the vuvuzela without affecting the audio you do want to hear.

According to Prosoniq, there are two ways to filter out the Vuvuzela noise: the first method being a notch filter. The problem with this method is that the Vuvuzela hum fluctuates and the frequencies of the audio commentary often overlap with the frequencies that the filter removes. As a result, you get a sound that is almost as annoying as the original Vuvuzela sound itself.

Here is an exampleoriginal and notch filtered.

VuvuX works differently – based on technology used in their audio de-mixing application sonicWORX Isolate, it isable to distinguish between voice, Vuvuzela hum and background noise by applying pattern detection and tracking.

Here is an example of VuvuX at work – original and using Vuvux. Not bad, and definitely better than the notch filter.

You can download VuvuX right here for free.

Now, if only we could come up with a filter to get rid of all the annoying stories, articles and blog posts about the vuvuz…. errr… sorry.
