摘要
when compressing a hoa data frame representation, a gain control (15, 151) is applied to each channel signal before it is perceptually encoded (16). gain values are transferred in a differential mode as side information. however, to initiate the decoding of such streamlined data frame absolute gain values are required, which must be encoded with a minimum number of bits. To determine said lower integer (ße) of bits, the hoa (c (k)) data frame representation is rendered in the spatial domain for virtual speaker signals being in a unit sphere, followed by normalization of the representation. data frame hoa (c (k)). then the lowest integer of bits is set to: (aa).
