Information processing program, device, and method

An information processing device comprising:

• a memory;
• and
• a processor coupled to the memory, the processor being configured to execute processing, the processing comprising:
• acquiring a sound signal collected by a microphone provided in a venue including a skating rink, and a first video obtained by photographing a competitor on the skating rink;
• estimating a takeoff-from-ice time and a landing-on-ice time of a jump performed by the competitor according to a silencing and a return of an ice sound based on the sound signal;
• and
• synchronizing time information of the sound signal with time information of the first video, and specifying each of a location corresponding to the takeoff-from-ice time and a location corresponding to the landing-on-ice time in a trajectory of a location of the competitor on the skating rink based on the first video.
