VOLUME CONTROL FOR USER INTERACTIVITY IN THE AUDIO CODING SYSTEMS Russian patent published in 2019 - IPC G10L19/08 

FIELD: physics.

SUBSTANCE: invention relates to the volume controlling means. Modifying the audio signal in response to the user input. Determining the loudness compensation gain, on the one hand, on the basis of the reference loudness or the reference gain, and on the other hand, on the basis of the modified loudness or modified gain. Modified loudness or modified gain depend on the user input. Loudness compensation gain is determined based on the audio signal metadata indicating whether the group contained in the audio signal should be, used or not used to determine the loudness compensation gain, wherein the group contains one or more audio elements; and / or the loudness compensation gain is determined based on the related to the preset audio signal metadata, wherein the preset relates to the set of containing one or more audio elements at least one group. Controlling the signal volume using the loudness compensation gain.

EFFECT: technical result consists in increase in the volume controlling efficiency for its compensation.
