#X text 442 79 1 Use define_loudspeakers to list the speaker positions.
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 444 222 2 For vbap \, give azimuth and elevation 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.;
