DYNAMIC PROCESSING IN DEVICES WITH DIFFERENT PLAYBACK FUNCTIONALITIES Russian patent published in 2022 - IPC H04R5/04 

FIELD: acoustics.

SUBSTANCE: invention relates to acoustics. The audio data processing method consists in obtaining by the control system and through the system of interfaces the configuration data of dynamic processing of individual speakers for each of the plurality of speakers of the listening environment. The configuration data contains a set of playback limit threshold values ​​for each speaker of the plurality of speakers. The control system determines the listening environment dynamics processing configuration data for a plurality of speakers, wherein the determination of the listening environment dynamics processing configuration data includes averaging the playback limitation thresholds over the plurality of speakers. Audio data is received by the control system through the system of interfaces, containing one or more audio signals and associated spatial data, the spatial data containing at least one of the channel data or spatial metadata. Performed by the dynamics processing control system on the audio data based on the configuration data of the dynamics processing of the listening environment to generate the processed audio data. The processed audio data is rendered by the control system for playback through a set of loudspeakers containing at least some of the plurality of loudspeakers. The rendered audio signals are transmitted through the interface system to a set of loudspeakers.

EFFECT: reducing unwanted shift in the spatial balance of the mix.
