Patent ID: 8660272

Claim:
A method of setting a parameter for an audio apparatus, the audio apparatus including: a delay processing unit which applies a delaying process and an amplifying process on an input audio signal in accordance with the set parameter and which outputs a processed audio signal; and an adding unit which adds the audio signal output from the delay processing unit to the input audio signal and which outputs an added audio signal to an outputting device that outputs, as sound, the audio signal output from the adding unit, the method comprising: performing a measuring process including: causing the outputting device to output measurement sound; and measuring a first impulse response at a sound receiving point; performing a specifying process including: analyzing the measured first impulse response; calculating a second impulse response at the sound receiving point when the outputting device outputs sound in case where a parameter is set in the audio apparatus and an audio signal indicative of the measurement sound is input to the audio apparatus; and specifying a parameter in accordance with the calculated second impulse response; and performing a setting process of setting the specified parameter in the delay processing unit.
