1. An information processing apparatus, comprising:
- a detecting section configured to detect an event sound from audio, the audio having been recorded when video was shot;
a calculating section configured to determine an event playback time at which an image associated with the event sound is played back in a video playback time sequence, the video playback time sequence corresponding to a playback speed lower than a shooting speed of the video; and
a determining section configured to determine an audio playback start time of the event sound during the video playback time sequence in accordance with the event playback time.
