Abstract
There is provided an information processing device, an information processing method, and a program that enable a system including two speakers and one microphone to measure a position of the microphone. An audio reception block receives an audio signal including a spreading code signal obtained by performing spread spectrum modulation on a spreading code, the audio signal being output from two audio output blocks existing at a known positions, and calculates a position of an audio reception unit on the basis of an arrival time difference distance that is a difference between distances to the two audio output blocks based on an arrival time at which a peak of cross-correlation is detected. The present invention can be applied to a game controller or an HMD.
