Classification: CPC G  H | IPC G  H

Claim 11:
12. An audio decoder apparatus comprising:
a processor; and
memory having stored therein instructions that configure the processor to obtain a bitstream, the bitstream comprising:
an encoded version of an audio signal,
a first dynamic range control, DRC, gain sequence, that was determined by an encoder side process applying the audio signal to a first DRC characteristic,
an index of the first DRC characteristic, wherein the index identifies or points to the first DRC characteristic,
a plurality of instances over time of an integrated loudness update, and
a flag, wherein when the flag has a first value the bitstream contains an encoder side loudness normalization gain, or when the flag has a second value the bitstream does not contain the encoder side loudness normalization gain.
