要約
(EN)

An acoustic processing system for an electronic device includes: an equalizer processor which boosts or cuts a digital signal which has been subjected to an acoustic process for each of frequency components; a low-pass filter which extracts a low-range signal from the signal from the equalizer processor and outputs the signal; a high-pass filter which extracts a high-range signal from the signal from the equalizer processor and outputs the signal; a high-frequency compressor which compresses the high-range signal; an adder which generates an addition of the low-range signal and the compressed high-range signal; and a speaker which outputs a sound in accordance with the addition of the signal.
