摘要: Embodiments relate to an audio processing unit that includes a buffer, bitstream payload deformatter, and decoding subsystem. The buffer stores at least one block of encoded bitstream. fill element begins with identifier followed by data. data flag identifying whether enhanced spectral band replication (eSBR) is be performed on content the block. A corresponding method for also provided.
