1. A signal encoding method for quantizing and encoding signal components resulting from resolution of an input signal into plural frequency components, comprising:
- splitting the signal components of the input signal into plural band units as encoding units;
computing an estimated value of the required number of bits as calculated from one band unit to another; and
adjusting the total number of bits required in encoding the signal components of the input signal based on the estimated value of the required number of bits as computed from one band unit to another.

Abstract
A signal encoding method for real-time encoding an acoustic signal using a small hardware. The spectral signal components of an input signal are split into encoding units as the units for encoding. At step ST102, an estimated value of the required number of bits is computed from one encoding unit to another. The total number of bits required in encoding the spectral signal components of the input signal is adjusted in steps ST103 and in the following steps based on the estimated value of the number of bits computed from one encoding unit to another.
