Abstract: The present technology relates to an information processing device and a data structure in which reproduction accuracy of a perceived sound can be improved.
The information processing device of the present technology includes a generation unit configured to generate a transfer characteristic file storing measurement data of transfer characteristics of a sound according to acoustic characteristics of a measurement space and condition information indicating a condition at a time of measuring the transfer characteristics. Furthermore, the information processing device of the present technology includes: a reproduction control unit configured to control reproduction of a sound by using measurement data acquired from a transfer characteristic file storing the measurement data of transfer characteristics of a sound according to acoustic characteristics of a measurement space and condition information indicating a condition at a time of measuring the transfer characteristics; and a presentation control unit configured to control presentation of information according to the condition information acquired from the transfer characteristic file. The present technology can be applied to, for example, a system that performs audio mixing of a movie.
