摘要：PROBLEM TO BE SOLVED: To perform processing based on waveform information even when DSD data is treated. SOLUTION: DSD data supplied from a DSD device 2 through an I/O 51 during recording is converted into PCM data by an LPF 57. For the conversion by the LPF 57, conversion small in number of taps and capable of easily executing calculation, i.e., rough conversion, is used. The PCM data obtained by the LPF 57 becomes PCM data for meter display, and the volume of the DSD data being recorded is meter-displayed by a meter display control part 58 based on the PCM data. The invention is applied to a personal computer capable of processing the DSD data. COPYRIGHT: (C)2006,JPO&NCIPI
