FIELD: physics.
SUBSTANCE: invention relates to processing of audio signals, in particular to devices and methods of classification and processing of audio signals, in particular to control of dialogue amplifier, virtualizer of ambient sound, volume equalizer and equalizer. Loudness equalizer controller and a control method are disclosed. In one embodiment, a loudness equalizer controller comprises an audio content classifier for real-time audio signal content type identification; and a control unit for adjusting the volume equalizer in continuous mode depending on the identified type of content. Control unit can be configured to positively correlate the dynamic gain of the loudness equalizer with types of informative content of the audio signal and negatively correlate the dynamic gain of the loudness equalizer with types of interfering content of the audio signal.
EFFECT: adjustment of volume equalizer in continuous mode depending on identified type of content.
