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.
