The example here defines loudspeakers in three dimensions (the first
parameter). For each speaker \, define its azimuth and elevation. Here
we have speakers front left and right with no elevation (-45 0 45 0)
and front and back with 45 degrees of elevation (0 45 180 45). Send
the data to vbap.;

#X text 429 36 Additionally it generates additional commands for controlling
a reverberated signal and has control to set the radial distance of
a sound.;
#X text 430 397 3) rvbap also will generate messages to control the
amount of reverberated signal to generate. This is meant to be used
with [matrix~] or [mtx_*~] from the IEMmatrix collection of externals.
;
#X text 431 255 2) For rvbap \, give azimuth and elevation and a distance
(1-inf \, default 1) for the desired location. Bang the first inlet
and vbap will output gain-factors for each speaker and the actual location
produced. This can be different from the desired one depending where
your speakers are.;
#X text 433 589 See rvbap-demo.pd for a more complex setup.;
#X text 429 467 To use it \, create a [mtx_*~] object that has double
the amount of outlets as you have speakers. Send the first half of
the matrix-signals to the speakers and the second half through a reverbarator
and add them to the respective speaker outs. The example shows this
in action for four speakers. Pay attention to the "set-element" subpatch
which translates the [rvbap] output to set matrix elements correctly.
