Abstract
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.
Claims20
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.
A generation method executed by a generation device, the generation method including:
- an acquisition step of acquiring room shape information regarding a shape of a room;
- a setting step of setting positions of sound producing points and sound receiving points of a virtual sound source in the room based on the room shape information acquired in the acquisition step;
- and
- a generation step of generating a room impulse response in the room based on the positions of the sound producing points and the sound receiving points set in the setting step and the room shape information.
A generation program for causing a computer mounted on a generation device to execute:
- acquisition processing of acquiring room shape information regarding a shape of a room;
- setting processing of setting 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 processing;
- and
- generation processing of generating 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 processing and the room shape information.
