Audio signal processing device, audio signal processing method, and program

摘要

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.
