Abstract
The sound signal processing method includes obtaining a sound signal of a sound source, convolving, according to a location of the sound source an impulse response of an early reflection sound with the sound signal to generate an early reflection sound control signal that reproduces an early reflection sound, and convolving an impulse response of a reverberant sound with the sound signal to generate a reverberant sound control signal that reproduces a reverberant sound.
Claims15
A sound signal processing method comprising:
- obtaining a sound signal of a sound source;
- convolving, according to a location of the sound source, an impulse response of an early reflection sound with the sound signal to generate an early reflection sound control signal that reproduces an early reflection sound;
- and
- convolving an impulse response of a reverberant sound with the sound signal to generate a reverberant sound control signal that reproduces a reverberant sound.
A sound signal processing device comprising:
- a sound signal obtainer that obtains a sound signal of a sound source;
- an early reflection sound control signal generator that convolves, according to a location of the sound source, an impulse response of an early reflection sound with the sound signal to generate an early reflection sound control signal that reproduces an early reflection sound;
- and
- a reverberant sound control signal generator that convolves an impulse response of a reverberant sound with the sound signal to generate a reverberant sound control signal that reproduces a reverberant sound.
A storage medium storing a sound signal processing program that causes a sound signal processing device to execute processing of:
- obtaining a sound signal of a sound source;
- convolving, according to a location of the sound source, an impulse response of an early reflection sound with the sound signal to generate an early reflection sound control signal that reproduces an early reflection sound;
- and
- convolving an impulse response of a reverberant sound with the sound signal to generate a reverberant sound control signal that reproduces a reverberant sound.
