Abstract:
A coding technology that efficiently codes an input sound signal irrespective of the characteristics thereof and can obtain a decoded sound signal that sounds less artificial to a listener. A coding method codes an input sound signal frame by frame of a predetermined time segment by a selected coding processing from a plurality of types of coding processing in the frequency domain, the coding method makes it possible for a selection unit to select coding processing which is different from the coding processing of the preceding frame as coding processing of the present frame if at least one of the magnitude of the energy of high frequency components of the input sound signal of the preceding frame and the magnitude of the energy of high frequency components of the input sound signal of the present frame is smaller than or equal to a predetermined threshold value.

Claim (Index 4):
The coding device according to  claim 3 , wherein the selection unit further makes possible a selection to select a same coding processing as coding processing of a preceding frame as coding processing of the present frame if the ascents and descents of the spectrum of the input sound signal of the present frame are moderate or the degree of concentration of the spectrum is medium.
