Methods and Apparatus for Rendering Audio Objects - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240334145 titled 'Methods and Apparatus for Rendering Audio Objects

The patent application describes a method for rendering audio data in a reproduction environment with multiple virtual source locations.

• Gain values are pre-computed for each virtual source based on reproduction speaker location data and stored for use during audio reproduction.
• Contributions from virtual source locations within an area defined by audio object position and size data are computed during run time.
• Gain values for each output channel are computed based on these contributions, corresponding to reproduction speakers in the environment.

Original Abstract Submitted

multiple virtual source locations may be defined for a volume within which audio objects can move. a set-up process for rendering audio data may involve receiving reproduction speaker location data and pre-computing gain values for each of the virtual sources according to the reproduction speaker location data and each virtual source location. the gain values may be stored and used during “run time,” during which audio reproduction data are rendered for the speakers of the reproduction environment. during run time, for each audio object, contributions from virtual source locations within an area or volume defined by the audio object position data and the audio object size data may be computed. a set of gain values for each output channel of the reproduction environment may be computed based, at least in part, on the computed contributions. each output channel may correspond to at least one reproduction speaker of the reproduction environment.
