#X text 441 59 1 Use the define_loudspeakers object or message 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.;
