DECODING AN ENCODED AUDIO SIGNAL USING DRC PROFILES

Decoding an encoded audio signal comprising frames of encoded audio data and metadata, the metadata including different dynamic range control, DRC, gains. Decoding according to a DRC gain profile corresponding to a desired output reference level. Determining a loudness related gain based on the indi...

Zusammenfassung:	Decoding an encoded audio signal comprising frames of encoded audio data and metadata, the metadata including different dynamic range control, DRC, gains. Decoding according to a DRC gain profile corresponding to a desired output reference level. Determining a loudness related gain based on the indication of the loudness level of the audio signal and the desired output reference level. Applying the loudness related gain to obtain loudness adjusted audio data that has the desired output reference level.
