Abstract
An audio encoding device includes a processor; and a memory which stores a plurality of instructions, which when executed by the processor, cause the processor to execute: detecting a plurality of lobes based on a frequency signal constituting an audio signal; calculating a masking threshold value of the frequency signal; allocating an amount of bits per unit frequency region to be allocated for encoding of the frequency signal on a basis of the masking threshold value; selecting a main lobe on a basis of bandwidth and power of the lobes; and controlling the encoding by reducing the amount of bits in a first region including a maximum value of the power in the main lobe.
