Space-aware dynamic range control system with priority

摘要

The audio signal is constrained in the audio coordinate system using a gain factor applied in the other audio coordinate system. The first and second components in the first audio coordinate system are generated from the third and fourth components of the audio signal in the second audio coordinate system. An amplitude threshold is determined that defines the maximum level for each of the third and fourth components. One or more gain factors are applied to each of the third and fourth components to produce the adjusted third component and the adjusted fourth component, and the first output channel and the second output channel in the second audio coordinate system are It is produced from the adjusted third and fourth components. Each of the first and second output channels is limited below the amplitude threshold from application of one or more gain factors.
