摘要： A reproducing apparatus includes a storage section, a judgment section, an analysis section, a classification section, an input section, and a reproduction section. The storage section stores a plurality of pieces of audio data. The judgment section judges, based on a length of each piece of audio data stored in the storage section, an analysis time interval for each piece of audio data. The analysis section analyzes the audio data in the analysis time interval judged by the judgment section. The classification section classifies the respective pieces of audio data into a plurality of predetermined classification items based on results of the analysis. The input section causes a user to select the classification item of the audio data to be reproduced. The reproduction section reproduces the audio data belonging to the classification item selected by the input section from a reproduction start point within the analysis time interval.
