Abstract

A METHOD AND/OR APPARATUS FOR ENCODING AND/OR DECODING AN AUDIO SIGNAL (301) IS DISCLOSED, IN WHICH A DOWNMIX GAIN IS APPLIED TO A DOWNMIX SIGNAL (304) IN AN ENCODING APPARATUS WHICH, IN TURN, TRANSMITS, TO A DECODING APPARATUS, A BITSTREAM (309) CONTAINING INFORMATION AS TO THE APPLIED DOWNMIX GAIN. THE DECODING APPARATUS RECOVERS THE DOWNMIX SIGNAL (307), USING THE DOWNMIX GAIN INFORMATION. A METHOD AND/OR APPARATUS FOR ENCODING AND/OR DECODING AN AUDIO SIGNAL IS ALSO DISCLOSED, IN WHICH THE ENCODING APPARATUS CAN APPLY AN ARBITRARY DOWNMIX GAIN (ADG) TO THE DOWNMIX SIGNAL, AND CAN TRANSMIT A BITSTREAM CONTAINING INFORMATION AS TO THE APPLIED ADG TO THE DECODING APPARATUS. THE DECODING APPARATUS RECOVERS THE DOWNMIX SIGNAL, USING THE ADG INFORMATION. A METHOD AND/OR APPARATUS FOR ENCODING AND/OR DECODING AN AUDIO SIGNAL IS ALSO DISCLOSED, IN WHICH THE METHOD AND/OR APPARATUS CAN ALSO VARY THE ENERGY LEVEL OF A SPECIFIC CHANNEL, AND CAN RECOVER THE VARIED ENERGY LEVEL.
