AUDIO CODING METHOD AND AUDIO DECODING METHOD Russian patent published in 2019 - IPC G10L19/08 H03M7/30 

FIELD: data processing.

SUBSTANCE: invention relates to media processing systems and particularly to adaptive processing of media data based on media data processing conditions for media data. These methods of adaptive processing of media data are based on separate data indicating state of media data. Media data processing device can determine whether processing of media data of any type has already been performed on the input version of media data. If it was, then the device can adapt processing of media data so that to cancel performance of processing of media data of certain type. If not, then device performs processing of media data of certain type. Device can create state of media data indicating type of media data processing. Device can transfer the state of media data and the output version of media data to the recipient device along the media processing circuit to support adaptive processing of media data by the recipient device.

EFFECT: enabling decoding of audio data normalized to matched loudness values.
