Abstract:
A sound signal processing device causes an amplifier to amplify a low frequency signal and synthesizes the amplified low frequency signal with a middle or high frequency signal so as to output the resultant output signal. A gain control section controls a gain of the amplifier on the basis of an amplitude of the output signal. As a result, it is possible to amplify the low frequency signal without any clipping in a receiving end device and without any unstable volume of a middle or high frequency component.
