Abstract: An audio system and method using indoor response estimation are disclosed. An acoustic feature prediction method of the audio system may include generating a detection signal based on an input signal and a modulation code; generating an acoustic signal based on the detection signal and outputting the acoustic signal to a plurality of speakers; measuring acoustic signals output from the speakers where the speakers are installed; and predicting acoustic features related to the speakers based on the measured acoustic signals and the modulation code.
