Sony patents method to make virtual audio match your room's shape
Sony describes a system that takes the physical shape of a room and calculates how sound should bounce off the walls. It uses this data to create a specific audio effect, known as a room impulse response, that makes virtual sounds feel like they are coming from real speakers in that space.
In the filing’s own words
To enable reproduction of a virtual sound source in consideration of an environment in which a user actually listens to a sound. A generation device includes an acquisition unit configured to acquire room shape information regarding a shape of a room; a setting unit configured to set positions of sound producing points and sound receiving points of a virtual sound source in the room based on the room shape information acquired by the acquisition unit; and a generation unit configured to generate a room impulse response in the room based on the positions of the sound producing points and the sound receiving points set by the setting unit and the room shape information.
What exactly they claim (claim 1)
1. A generation device, including: an acquisition unit configured to acquire room shape information regarding a shape of a room; a setting unit configured to set positions of sound producing points and sound receiving points of a virtual sound source in the room based on the room shape information acquired by the acquisition unit; and a generation unit configured to generate a room impulse response in the room based on the positions of the sound producing points and the sound receiving points set by the setting unit and the room shape information.
