Kind Code:
A1
Abstract:
Provided is an audio reproduction device that is able to generate a sound having desired characteristics from a given speaker. This audio reproduction device is provided with: a signal amplifier that amplifies an input signal; a characteristic measurement instrument that acquires characteristics of a speaker device on the basis of a supply signal obtained using, as an input signal, a measurement signal having a specific frequency characteristic; a configuration analyzer that identifies the configuration of the speaker device on the basis of a result of the acquisition by the characteristic measurement instrument; a delay characteristic calculator that calculates a delay characteristic of the speaker device in accordance with the identified configuration of the speaker device; a compensation parameter generator that generates a compensation parameter on the basis of the difference between the delay characteristic calculated by the delay characteristic calculator and a target delay characteristic; and a compensator that compensates the input signal to be inputted to the signal amplifier on the basis of the compensation parameter generated by the compensation parameter generator.
