1. An information processing device, comprising:
a calculation unit configured to calculate, based on positional information indicating a plurality of observation positions in a space and an audio signal of sound observed at each of the plurality of observation positions, an amplitude or phase of the sound at each of a plurality of positions in the space at a first time interval;
an event detection unit configured to detect an event; and
an adjustment unit configured to perform, based on the detection of the event is detected, control such that the amplitude or the phase is calculated at a second time interval shorter than the first time interval.
