ABSTRACT:
The method and apparatus of generating a naturally sounding output audio signal (120) by adding missing output components (125) in a predetermined first frequency range (R1) to an input signal (100), set a first output energy measure (S1), over a predetermined first time interval (dt1), of the output components (125) generated based upon a first input energy measure (E1) calculated over a predetermined second time interval (dt2) of second input components (104), in a predetermined third frequency range (R3) of the input audio signal (100).
