PROBLEM TO BE SOLVED: To simplify processing required for normalization of a voice file in which recording is finished. SOLUTION: A digital recording apparatus 100 of the invention comprises: a microphone 110 for converting collected sound to an analog sound signal; an AD converter 202 for converting the analog sound signal converted by the microphone to a digital sound signal; a control section 150 for acquiring the digital sound signal from the AD converter; a memory 204 for storing the acquired digital sound signal. The control section includes: a sound signal storing section 210 for storing the digital sound signal in the memory; and a statistic data generating section 212 in which a feature value of the digital sound signal is extracted in real time, and in which the statistic data is generated according to the feature value. The statistic data based on the feature value which forms the digital sound signal is generated in real time at the same timing when the digital sound signal is stored in the memory.
