WWWVBAPThe Ultimate VBAP WWW Demonstration
VBAP - Vector Base Amplitude Panning is a method for positioning virtual sources to multiple loudspeakers. The number of loudspeakers can be varying and they can be placed in an arbitrary 2-D or 3-D positioning. VBAP produces virtual sources that are as sharp as is possible with current loudspeaker configuration and amplitude panning methods, since it uses at one time the minimum number of loudspeakers needed, one, two, or three. The VBAP method has been developed by Ville Pulkki. VBAP implementations are available at least for Csound and MAX / MSP.
At the moment, the WWWVBAP demonstration only allows 3-D setups to be used. Therefore, you will need a multichannel audio system with minimum of 3 and maximum of 8 channels (loudspeakers). At least one of the speakers has to be located above the azimuth plane (its elevation angle has to be greater than zero).
In addition you will need a sound playing software that supports multichannel
AIFF files. The WWWVBAP sends audio files with mime-type
in case you want to adjust your browser preferences. Normally, you shoul be prompted
with "Save file"-dialog.
