Sound volume correcting device, sound volume correcting method, sound volume correcting program, and electronic apparatus

摘要

A sound volume correcting device includes: a variable gain unit controlling a gain of an input audio signal on the basis of a gain control signal; a voice average level detector detecting an average level of a human voice signal in the input audio signal; and a gain control signal generator generating the gain control signal for controlling the gain of the input audio signal using the average level of the human voice signal detected by the voice average level detector as a reference level and supplying the generated gain control signal to the variable gain unit.
