ABSTRACT:
A encoded-sound-code decoding method comprises a first step of performing a decoding process on a predetermined number of sample codes starting from a sound-reproduction start position at some midpoint of a sequence of codes based on a predetermined initial value of a sound parameter; a second step of making comparison between a judgment parameter corresponding to a decoding result and a predetermined threshold value thereby determining whether the decoding result is proper or not; a third step in which, in response to a determination that the decoding result is not proper, the initial value of the sound parameter used at the first step is modified and then the processes of the first and second steps are performed; and a fourth step in which, after repetitions of the process of the third step until the decoding result is determined to be proper, the codes are sequentially decoded from the sound-reproduction start position at some midpoint of the code sequence.
