OPTIMISATION OF VOLUME AND DYNAMIC RANGE THROUGH VARIOUS PLAYBACK DEVICES Russian patent published in 2017 - IPC H03G9/00 G06F3/16 G10L13/33 G10L21/364 G10L15/20 

FIELD: physics.

SUBSTANCE: method is performed by analysing metadata to determine, whether or not the metadata actually are or include profile metadata indicating the target profile, wherein the profile metadata are suitable for performing, at least, one of volume control, volume normalization, or dynamic range control of audio data in accordance with the target profile. The target profile determines the target loudness and/or, at least, one target characteristic of the dynamic range subjected to the rendering of the audio data version for playback by the audio playback device from the group of audio playback devices.

EFFECT: ensuring the reception of bit streams.
