ABSTRACT:
The input signal of one of the plural channels is converted by a converting circuit into frequency components which are separated into tonal components and noise components in a signal comment separating circuit. The tonal components and the signal components are encoded by a tonal component encoding circuit and a noise component encoding circuit, respectively. The amount of bytes allocated to the noise components in the respective channels is determined by a byte allocation circuit based upon time changes of the sum of the scale factors of the respective channels.
