VuvuzeLAUTLOS Description

An audio plug-in that filters the Vuvuzela noise The reduction of disturbing noise, especially for mobile telephones and digital hearing aids, is one of the core competences of the Institute of Communication System and Data Processing (IND). The list of noise sources is long, but since the soccer world cup has begun it is clearly dominated by the Vuvuzelas. Their deafening noise even renders a TV broadcast an acoustic challenge.An algorithm which has been developed at the institute is now able to reliably suppress the disturbing Vuvuzela noise during soccer matches. The VuvuzeLAUTLOS program implements an adaptive comb filter according to the LTP principle (long term prediction) for the noise-relevant frequency range which consists of the fundamental frequency and the first five harmonics. The filter "strength" is controlled adaptively to minimize distortion of the remaining audio signal. VuvuzeLAUTLOS is currently implemented as VLC plugin.Here is a short sequence of steps that has to be followed for installing VuvuzeLAUTLOS on your Mac: · Open the folder Programs with Finder· VLC -> right mouseclick -> Show Package Contents· Copy the .dylib file in the new Finder Window to: Contents -> MacOS -> modules · Start VLC: 1) Activate plugin: 2) VLC -> Preferences (or CMD + ,) 3) Bottom left: Show preferences: all· Under Audio -> Filter: activate VuvuzeLAUTLOS· Save· restart VLC!
