[PD] [announce] Vector Base Amplitude Panning

[Juha Vehviläinen]

Hi all,

I'm currently working at the Laboratory of Acoustics and
Audio Signal Processing at Helsinki University of Technology.
This is also the place where Ville Pulkki, the creator of VBAP
(Vector Base Amplitude Panning) works.

The unavoidable consequence is, there's now a port for the latest
VBAP to Pure Data. Here's an introduction, in Ville's words:

"Vector Base Amplitude Panning (VBAP) 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."

Advantages over the one in ggee are, at least:

- object for defining loudspeaker positions
- spread-parameter
- new code (up to date with the max/csound-versions)

The included vbap-help.pd uses matrix and matrix~ from zexy.

(the tarball has sources and a binary for irix, more binaries
 will appear later..)

cheers
