   VBAP was developed by Ville Pulkki at Aalto University, Helsinki, in 2001.
   It works by distributing the signal to the speakers nearest to the desired
   direction with appropriate weightings, aiming to create a maximally sharp 
   phantom source by using as few speakers as possible:

   the panner direction. The width parameter controls the opening angle of
