Classification: CPC G  H | IPC G  H

Claim 0:
1. A method comprising:
receiving, by a decoding device, encoded audio information and metadata associated with an audio signal, the metadata including one or more parameter values specifying dynamic range compression (DRC) according to a first profile associated with a first reference reproduction level, and one or more parameter values specifying DRC according to a second profile associated with a range of reference reproduction levels;
selecting the one or more parameter values specifying DRC according to the second profile when a playback reference reproduction level is within the range of reference reproduction levels associated with the second profile, wherein the playback reference reproduction level is controlled through an interface to the decoding device;
applying, by the decoding device, a decoding process to the encoded audio information to obtain subband signals representing spectral content of the audio signal;
modifying, by the decoding device, the subband signals using the one or more DRC parameter values specifying DRC according to the second profile to obtain modified subband signals with changed dynamic range characteristics; and
applying, by the decoding device, a synthesis filter bank to the modified subband signals to obtain a decoded audio signal.
