PROBLEM TO BE SOLVED: To provide a data decoding device which can reproduce compressed digital sound data at a low cost for a long time. SOLUTION: This data decoding device 100 is equipped with a digital interface 106 for inputting compressed data reproduced by a CD player 200 which reproduces a CD 206 where digital data compressed in MP3 format are recorded, an MP3 decoder 108 which decodes the compressed data inputted by the digital interface 106 into uncompressed data, and a control circuit 105 which controls the reproducing speed of the compressed data by the CD player according to the data compression rate of the compressed data and controls the amount of the compressed data inputted to the MP3 decoder 108 through the digital interface 106.
