audio signal encoding method, audio signal decoding method, encoding device, decoding device, audio signal processing system, audio signal encoding program, and audio signal decoding program. The present invention relates to a frame immediately preceding a target coding frame to be coded by a first coding unit operating under a linear predictive coding scheme that is coded by a second coding unit operating under a coding scheme. Unlike the linear predictive coding scheme, the target coding frame can be coded under the linear predictive coding scheme by initializing the internal state of the first coding unit. therefore, coding processing performed under a plurality of coding schemes including the linear predictive coding scheme and a coding scheme other than the linear predictive coding scheme can be performed.
