IMAGE-BASED SOUNDFIELD RENDERING
Abstract:
An audio control system may include an imaging sensor to capture an image of an environment containing loudspeakers connected to the audio control system. A listening position subsystem may process the captured image to identify a listening position within the environment. A speaker position subsystem may process the captured image to determine a physical location of each loudspeaker relative to the identified user listening position. A signal processing subsystem may modify an output signal driving the loudspeakers to steer a soundfield generated by the loudspeakers. The audio control system may include a processor, memory, and/or hardware components to implement the various subsystems such that, at the identified user listening position, a perceived location of one of the loudspeakers is mapped to a location that is different than its physical location.
