FIELD: audio equipment.
SUBSTANCE: invention relates to means for encoding and decoding audio data. Bitstream is obtained by means of an audio decoding device. Bitstream includes a syntax element that identifies whether vector quantization or scalar quantization has been performed. Performing, by means of an audio decoding device and based on the syntactical element, or vector dequantization, or scalar dequantization with respect to the spatial component given in the region of spherical harmonics. Prepare by rendering one or more sound feeds to the speakers. Output one or more audio feeds to the speakers to one or more speakers.
EFFECT: technical result is to improve the efficiency of audio data encoding.
