摘要
A high-efficiency encoding method that distributes variable bits among channels to the samples in the time regions or the frequency regions of a plurality of channels (CH1 to CH8). The high-efficiency encoding method quantizes the bit distribution amount of the channels (CH1, CH3, CH6) that distributes the amount of bits larger than a predetermined reference amount (e.g., 147 kbps) by decomposing it into a first bit distribution amount that does not exceed 147 kbps and a remaining second bit distribution amount (which exceeds 147 kbps). The high-efficiency encoding method makes it possible to reproduce compression signals maintaining high-quality tone by utilizing the bit distribution among the channels as well as to reproduce the signals without deteriorating the quality of tone even in a decoder that distributes the bits in the channels using a bit rate smaller than a predetermined value for each of the channels that are frequently used.
