There is provided an acoustic processing device capable of maintaining volume and reproducing audio signals with good sound quality independent of the media audio encoding format, sound source type or sound source volume setting. In the acoustic processing device (1), a limiter control signal generation section (5) generates a limiter control signal for applying rapid variation correction determined based on a short-term signal level variation of an audio signal of a sound source and slow variation correction determined based on a long-term signal level variation of the audio signal of the sound source, and volume control sections (7) and (8) apply the generated limiter control signal to the audio signal and control the volume of the sound source.
