Abstract

AN AUDIO ENCODER FOR ENCODING AN AUDIO SIGNAL COMPRISES A FIRST CODING BRANCH (400), THE FIRST CODING BRANCH COMPRISING A FIRST CONVERTER (410) FOR CONVERTING A SIGNAL FROM A TIME DOMAIN INTO A FREQUENCY DOMAIN. FURTHERMORE, THE AUDIO ENCODER COMPRISES A SECOND CODING BRANCH (500) COMPRISING A SECOND TIME/FREQUENCY CONVERTER (523). ADDITIONALLY, A SIGNAL ANALYZER (300/525) FOR ANALYZING THE AUDIO SIGNAL IS PROVIDED. THE SIGNAL ANALYZER, ON THE HAND, DETERMINES WHETHER AN AUDIO PORTION IS EFFECTIVE IN THE ENCODER OUTPUT SIGNAL AS A FIRST ENCODED SIGNAL FROM THE FIRST ENCODING BRANCH OR AS A SECOND ENCODED SIGNAL FROM A SECOND ENCODING BRANCH. ON THE OTHER HAND, THE SIGNAL ANALYZER DETERMINES A TIME/FREQUENCY RESOLUTION TO BE APPLIED BY THE CONVERTERS (410, 523) WHEN GENERATING THE ENCODED SIGNALS. AN OUTPUT INTERFACE INCLUDES, IN ADDITION TO THE FIRST ENCODED SIGNAL AND THE SECOND ENCODED SIGNAL, A RESOLUTION INFORMATION IDENTIFYING THE RESOLUTION USED BY THE FIRST TIME/FREQUENCY CONVERTER AND USED BY THE SECOND TIME/FREQUENCY CONVERTER.
