Abstract

See full text

A vehicular audio-amplifier controller includes: a delay buffer that stores a sound signal supplied from a signal source; a first processing unit that applies an absolute value process to the supplied sound signal; a second processing unit that applies a low-pass filter process and an offset process to a processing result of the first processing unit; a power supply controller that performs control to change a voltage value of a vehicular power supply according to at least a signal value processed by the second processing unit and a type of the signal source; and a sound signal output unit that outputs a sound signal stored in the delay buffer with only a delay time that is determined based on a power supply control process time of the power supply controller.
