Abstract:
A coding apparatus, including a memory and a processor that, when executing instructions stored in the memory, performs operations including encoding low-band transform coefficients in a first band and calculating, for each extension-band subband obtained by splitting an extension band, a threshold amplitude based on an analysis of statistics on extension-band transform coefficients included in the subband. The processor further compares, for each of the extension-band subbands, an amplitude of the extension-band transform coefficients with the threshold amplitude to extract a representative transform coefficient, updates, when a number of the extracted representative transform coefficients is less than a predetermined number, the threshold amplitude, performs processing to again extract a transform coefficient using the updated threshold amplitude, calculates, for each of the extension-band subbands, a value of correlation between the representative transform coefficient and a normalized encoded low-band transform coefficient.

Claim (Index 2):
The coding apparatus according to  claim 1 , wherein the threshold calculation section updates the threshold such that a smaller threshold is set for a larger shortage number of the representative transform coefficients with reference to the predetermined number.
