摘要：
An audio signal processing device includes: an input section to which an audio signal is input; a bias processing section configured to add a bias signal to the audio signal; a calculation section configured to perform a power calculation on the audio signal to which the bias signal has been added by the bias processing section; and an adding unit configured to add the audio signal on which the power calculation is performed by the calculation section to the audio signal having been input to the input section.
