Abstract:
In an audio encoder, for audio content received in a source audio format, default gains are generated based on a default dynamic range compression (DRC) curve, and non-default gains are generated for a non-default gain profile. Based on the default gains and non-default gains, differential gains are generated. An audio signal comprising the audio content, the default DRC curve, and differential gains is generated. In an audio decoder, the default DRC curve and the differential gains are identified from the audio signal. Default gains are re-generated based on the default DRC curve. Based on the combination of the re-generated default gains and the differential gains, operations are performed on the audio content extracted from the audio signal.

Claim (Index 7):
A non-transitory computer readable storage medium, storing software instructions, which when executed by one or more processors cause performing:\n receiving, by an audio decoder operating in a playback channel configuration different from a reference channel configuration, an audio signal for the reference channel configuration, the audio signal including audio sample data for each channel of the reference channel configuration, and encoder-generated dynamic range control (DRC) metadata, the encoder-generated DRC metadata comprising DRC gains for a plurality of channel configurations, including a set of DRC gains for the playback channel configuration and a set of DRC gains for the reference channel configuration; selecting, from the DRC gains for the plurality of channel configurations, the set of DRC gains for the playback channel configuration; and applying the set of DRC gains for the playback channel configuration as a part of overall gains applied to the audio sample data to generate output audio sample data for each channel of the playback channel configuration; wherein each set of DRC gains corresponds to a DRC gain profile.
