Abstract
A sound signal processing method includes: obtaining a sound signal; obtaining impulse response data that was measured in a predetermined space before the sound signal is obtained; generating an early reflected sound control signal not including a reverberant sound by convolving impulse response data of an early reflected sound among the obtained impulse response data into the obtained sound signal.
Claims20
A sound signal processing method, comprising:
- obtaining a sound signal;
- obtaining impulse response data that was measured in a predetermined space before the sound signal is obtained;
- and
- generating an early reflected sound control signal by convolving impulse response data of an early reflected sound among the obtained impulse response data that was measured in the predetermined space before the sound signal is obtained into the obtained sound signal,
- wherein the impulse response data was measured by using a directional microphone disposed on or alongside a wall of the predetermined space.
