PROBLEM TO BE SOLVED: To provide an apparatus for encoding and decoding audio signals and a method thereof.SOLUTION: Spatial information is encoded into a bitstream, and the bitstream includes different syntax related to time, frequency and spatial domains. The bitstream includes one or more data structures (e.g., frames) that contain ordered sets of slots for which parameters can be applied. A data structure type indicator is inserted to the bitstream. The data structure includes position information that can be used by a decoder to identify a correct slot for which a given parameter set is applied. The slot position information is encoded with either a fixed number of bits or a variable number of bits based on the data structure type indicated by the data structure type indicator. For variable data structure types, the slot position information is encoded with a variable number of bits based on the position of the slot in the ordered set of slots. |
