Abstract:
In general, techniques are described for coding a number of code vectors for independent frame of higher order ambisonic coefficients. An audio decoding device comprising a memory and a processor may perform the techniques. The memory may store a first frame of a bitstream and a second frame of the bitstream. The processor may extract, from the first frame, one or more bits indicative of whether the first frame is an independent frame that includes information specifying a number of code vectors to be used when performing vector dequantization with respect to the vector. The processor may also extract, from the first frame without referencing the second frame, the information specifying the number of code vectors.
