Audio signal processing device, audio signal processing method, and program
First Claim
1. An audio signal processing device comprising:
- two audio signal processing units that serially perform a processing with respect to an input audio signal, and obtain an output audio signal for driving a speaker,wherein one audio signal processing unit of the two audio signal processing units performs, with respect to the input audio signal, a correction process through a filter that realizes a reverse characteristic of an impulse response measured at a first measurement position that is a front position of the speaker, andthe other audio signal processing unit performs, with respect to the input audio signal, a correction process through a filter that realizes a reverse characteristic of an impulse response measured at a second measurement position different from the first measurement position that is a front position of the speaker.

Abstract
An audio signal processing device includes two audio signal processing units that serially perform a processing with respect to an input audio signal, and obtain an output audio signal for driving a speaker. One audio signal processing unit of the two audio signal processing units performs, with respect to the input audio signal, a correction process through a filter that realizes a reverse characteristic of an impulse response measured at a first measurement position that is a front position of the speaker. The other audio signal processing unit performs, with respect to the input audio signal, a correction process through a filter that realizes a reverse characteristic of an impulse response measured at a second measurement position different from the first measurement position that is a front position of the speaker.

11. An audio signal processing method, comprising:
-
two audio signal processing steps of serially performing a processing with respect to an input audio signal and obtaining an output audio signal for driving a speaker, wherein in one audio signal processing step of the two audio signal processing steps, a correction process is performed with respect to the input audio signal through a filter that realizes a reverse characteristic of an impulse response measured at a first measurement position that is a front position of the speaker, and in the other audio signal processing step, a correction process is performed with respect to the input audio signal through a filter that realizes a reverse characteristic of an impulse response measured at a second measurement position different from the first measurement position that is a front position of the speaker.

12. A non-transitory computer-readable medium having embodied thereon a program, which when executed by a computer allows the computer to function as two audio signal processing units that serially perform a processing with respect to an input audio signal and obtain an output audio signal for driving a speaker,
wherein one audio signal processing unit of the two audio signal processing units performs, with respect to the input audio signal, a correction process through a filter that realizes a reverse characteristic of an impulse response measured at a first measurement position that is a front position of the speaker, and the other audio signal processing unit performs, with respect to the input audio signal, a correction process through a filter that realizes a reverse characteristic of an impulse response measured at a second measurement position different from the first measurement position that is a front position of the speaker.
