Method and apparatus for generating audio components

摘要

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 (R 1 ) to an input signal ( 100 ), set a first output energy measure (S 1 ), over a predetermined first time interval (dt 1 ), of the output components ( 125 ) generated based upon a first input energy measure (E 1 ) calculated over a predetermined second time interval (dt 2 ) of second input components ( 104 ), in a predetermined third frequency range (R 3 ) of the input audio signal ( 100 ).
