FIELD: acoustics; electronics.
SUBSTANCE: invention relates to electronics, particularly to audio signal volume adjusting devices. Device contains classifier for audio signal content type identification, control unit to adjust volume in continuous mode. Control unit is made with possibility of volume equalizer dynamic amplification factor positive correlation with audio signal information content types and volume equalizer dynamic amplification factor negative correlation with audio signal interfering content types. At that, classification is performed by calculation of reliability values weighting factors taking into account information significance. Device also contains dialogue amplifier, ambient sound virtualize, volume equalizer, equalizer, type and parameter smoothing units, timer. Classifier comprises audio content classifier and context classifier. Content classifier consists of objects short-term signs selector and short-term classifier. Context classifier includes statistical data selector and long-term classifier. Dialogue amplifier comprises signal minimum tracking unit.
EFFECT: increasing audio content clarity and audibility.
