PROBLEM TO BE SOLVED: To enable performing the decoding of data from the arbitrary position of compression-encoded data by reproducing the data received from the arbitrary frame of the compression-encoded data based on decode parameters in a header after receiving the header. SOLUTION: Decode parameters and Twin VQ frame data are transmitted from a sequencer 11 and when the decode parameters are transmitted, they are temporarily stored in a memory 60. An acoustic data processing part 8 receives the decode parameters, that is, data including a sampling rate and a bit rate before it reproduces karaoke music to store them in the memory. In this state, the part 8 decodes the Twin VQ frame data from the sequencer 11 based on these parameters. When the parameters are temporarily stored in the memory, even when the position of a pointer on a sound control track is changed by a fast forwarding operation or the rewinding operation or the like thereafter, the part 8 can perform the decoding of data from a frame data corresponding to that position. |
