Apparatus and method for an automated control of a reverberation level using a perceptional model

An apparatus for processing an audio input signal comprising one or more audio channels to obtain an audio output signal according to an embodiment is provided. The apparatus comprises a reverberation gain determiner (110) configured to determine reverberation gain information depending on the audio input signal. Moreover, the apparatus comprises a signal processor (120) configured to obtain the audio output signal depending on the reverberation gain information by adding artificial reverberation to the audio input signal or to a preprocessed audio signal, which depends on the audio input signal.
