Audio encoding apparatus

Abstract

An audio encoding apparatus that encodes audio signals of a plurality of channels, includes an adaptive bit allocation control unit that adaptively controls a number of encoding bits assigned to the audio signal of each channel in accordance with perceptual entropy of the audio signal of each of the channels, a fixed bit allocation control unit that fixedly controls the number of encoding bits assigned to the audio signal of each of the channels in predetermined allocations, and a channel encoding unit that encodes the audio signal of each of the channels based on the number of adaptive allocation bits assigned by the adaptive bit allocation control unit and the number of fixed allocation bits assigned by the fixed bit allocation control unit.
