Abstract
A quantization error correcting device corrects quantization error included in audio information at the time of decoding. The audio information is divided into a plurality of frequency bands and compressive-encoded for each frequency band with bit allocation determined based on audible frequency characteristic. The device includes: a detecting unit for detecting, based on bit allocation information indicating bit allocation and encoded values of the compressive-encoded audio information, a range of quantization error indicating a range in which audio information value before compressive-encoding corresponding to the encoded value exists; and an outputting unit for outputting a decoded value corresponding to one of the encoded values based on the detected range of quantization error and the ranges of quantization errors of other correlated ones of the encoded values.
