Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method and device for additionally processing the simple channel data whose processing scale is reduced as for a compressed sound stream. SOLUTION: The audio re-coding processor comprises a means 14 for holding 1st header information of a compressed sound frame, a compressed audio channel data and a 1st error correcting data, a coding processing means 31 for processing the conversion of uncompressed sound signal and outputting an additional compressed channel data and an error correction protective area data, a means 27 for creating a 2nd error correction processing data reflecting the error correction protective area on the 1st error correcting data, a means 51 for rewriting the 1st header information with the 2nd header information on which it is reflected that the additional compressed channel data has been added, and a re-packing means 29 for creating a new compressed sound stream by inputting the 2nd header information, the 2nd error correction processing data, the compressed audio channel data and the additional compressed channel data to the audio re-coding processor.
