FIELD: sound recording technologies.
SUBSTANCE: when compressing the HOA data frame representation, a gain control is applied to each channel signal before it is perceptually encoded. The gain values are transmitted in differential mode as side information. To determine such a smallest integer (βe) of bits, the representation of the HOA data frame (C(k)) is reproduced in the spatial domain as virtual speaker signals lying on a unit sphere, followed by normalization of the HOA data frame representation (C(k)).
EFFECT: providing the smallest integer number of bits necessary to represent non-differentiable gain values.
