FIELD: signal processing.
SUBSTANCE: present invention relates to means for signal processing. Distribution information is generated in an audio object frame to be processed, based on information about location of an object in the audio object frame to be processed and any distribution information in another frame different from the audio object frame to be processed, scaling information and information about a size of the audio object. Generated distribution information is angle information indicating a size range of a sound image of the audio object.
EFFECT: increase in the efficiency of signal processing.
