Information processing apparatus, information processing method, and program

摘要

An information processing apparatus (1) is disclosed which stores externally captured direct stream digital data (12) into a file (11) for management purposes. The apparatus includes: a file generating section (52) generating the file (11) in such a manner as to hold the direct stream digital data (12) read and written in increments of a data volume higher than one sample of data (S11) according to a direct stream digital method, the file (11) being further arranged to have a storage area (13) for accommodating audio data encoded by an encoding method different from the direct stream digital method (14); and an audio data generating section (58) generating the audio data encoded by the encoding method different from the direct stream digital method in accordance with the direct stream digital data (S4), the audio data generating section further storing the generated audio data into the storage area of the file generated by the file generating section (S5).
