Abstract:
1. An acoustic processing device comprising: a level signal generation section configured to generate a first control signal generation section configured to generate, based on the signal level variation in the first variation signal, a first control signal for performing rapid variation correction for the signal level of the audio signal; a second control signal generation section configured to generate, based on the signal level variation in the second variation signal, a second control signal for performing slow variation correction for the signal level of the audio signal; a limiter control signal generation section configured to multiply the second control signal generated by the second control signal generation section and the first control signal generated by the first control signal generation section to generate a limiter control signal capable of applying the rapid variation correction and slow variation correction to the signal level of the audio signal; and a volume control section configured to perform volume control of the audio signal by applying the limiter control signal to the audio signal, wherein the second control signal generation section includes:
