    = 2
    
    Object-based audio, polar version, per  section 8 of the ITU radio Audio Definition Model defined in ITU-R BS.2076-1.  For details, see the ITU standard and AES70-1, section 5.5.9.
 - Azimuth is angle in the horizontal plane with 0 degrees as straight ahead, and positive angles to the left (or anti-clockwise) when viewed from above.  
 - Elevation is angle in the vertical plane with 0 degrees horizontally ahead, and positive angles going up.
