Abstract

Provided is an acoustic signal encoding method capable of encoding an acoustic signal having a large number of channels at a sufficient bit rate. In this acoustic signal encoding method, the acoustic signal of a plurality of channels are encoded by executing encoding device. Firstly, the masking threshold corresponding to the spatial masking effect of hearing is calculated. Then, the amount of information for allocating the acoustic signal of the plurality of channels to each channel is determined by the calculated masking threshold. Then, the acoustic signal of the plurality of channels are encoded with the amount of information allocated to each. This makes it possible to encode the acoustic signal of the plurality of channels at a sufficient bit rate.
