ABSTRACT:
An encoding apparatus which utilizes masking characteristics of channels for bit allocation in order to encode digitally sampled audio signals of at least two channels in units of an audio frame, allocates the bits to the divided bands of the first and second channels, detects a channel having a masking to noise ratio in which the respective divided bands exceed the masking threshold value based on the first masking threshold value with respect to the first channel and the second masking threshold value with respect to the second channel, and uses all the number of the bits which are not used for the channel among the total number of the bits of one audio frame for bit allocation of the other channel, thereby improving the quality of the sound even when an audio signal which includes many high frequency components is reproduced.
