The very much unofficial VBAP logo that has been strongly criticized by the engineering community will lead you to the official VBAP introduction

WWWVBAP

The Ultimate VBAP WWW Demonstration

Introduction

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.

What do you need to use this demo?

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 audio/multichannel-aiff in case you want to adjust your browser preferences. Normally, you shoul be prompted with "Save file"-dialog.

  

Step 1: Loudspeaker setup

First you need to define your loudspeaker setup. You will need at least 3 speakers in order to enjoy the incredible VBAP sound experience. Fulfill the azimuth (-180 - 180) and elevation angles (degrees) (0 - 90) for your setup. At least one of the elevation angles has to be greater than zero.
