A band splitting section a01 splits an encoder input signal s00, entered into a subband encoding apparatus, into k band components. The band splitting section a01 outputs a subband signal s01 for each of n (<k) split bands, where n is determined by a processible upper-limit frequency on each application. A scale factor producing section a02 detects a maximum amplitude level of the subband signal s01 for each of n split bands. Then, the scale factor producing section a02 produces scale factor information s02 representing a normalized scale factor. A bit allocation producing section a04 outputs bit allocation information s04 for each of n split bands. A bit allocation value 0 is assigned to each of (n+1) to k split bands. A requantizing section a06 requantizes the subband signal s01 for each split band. A frame constructing section a07 constructs a coded frame.
