Patent ID: 7315817

Claim:
A sound encoder comprising: an encoding means for encoding a plurality of parameters that represent an input sound signal representing a sound so as to produce a plurality of codes on a frame-by-frame basis; an order determination device that determines and outputs an order in which the plurality of codes are to be multiplexed into a multiplexed code based on one of the produced plurality of codes for each frame on a frame-by-frame basis; a multiplexing device that multiplexes the plurality of codes one by one into a multiplexed code in the order determined by said order determination means for each frame on a frame-by-frame basis, and that outputs the multiplexed code; and an error correction coding device that produces an error correction code for the multiplexed code and that outputs the multiplexed code with the error correction code added thereto as a sound code on a frame-by-frame basis.
