Title:
INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/218917
Kind Code:
A1
Abstract:
The present technology relates to an information processing device, an information processing method, and a program that make it possible to reproduce reproduction sound in an acoustic space with high accuracy. The information processing device according to the present technology comprises a harmonic signal generation unit that generates a first signal by convolving transfer characteristics of harmonic distortion in an acoustic space with an input signal and a combining unit that combines the first signal and a second signal obtained by convolving transfer characteristics of sound excluding the harmonic distortion in the acoustic space with the input signal. The harmonic signal generation unit convolves the transfer characteristics of the harmonic distortion for each order with the input signal processed in correspondence with the order of the harmonic distortion. The present technology can be applied to, for example, a system that carries out audio mixing for content such as movies.
