OPTIMIZATION OF VOLUME AND DYNAMIC RANGE THROUGH VARIOUS PLAYBACK EQUIPMENT Russian patent published in 2018 - IPC G10L19/02 H03G9/00 

FIELD: data processing.

SUBSTANCE: invention relates to the field of processing audio signals. Metadata container begins with a sync word identifying the beginning of the metadata container, one or more metadata operating data includes a parameter indicating a dynamic range compression (DRC) profile selected from among a plurality of DRC profiles, wherein each of the plurality of DRC profiles corresponds to a unique compression curve with associated time constants, and said one or more operating metadata data follows the security data, which can be used to decrypt, authenticate, or verify the validity of said one or more operational metadata operating data.

EFFECT: technical result is to improve the processing efficiency of audio signals.
