order and degree
degree parameters appear in
audioBlockFormat only for the 'HOA' typeDefinition.
The meaning of order and degree values is based on the following definition of real-valued spherical harmonics:
- is the order value, is the degree value, is azimuth, and is elevation
- is the normalization parameter for the given order and degree
- is the associated Legendre function for the given order and degree.
The associated Legendre functions are defined as:
with the Legendre polynomial and without the Condon-Shortley phase term .
