Apple has been awarded a new patent in MacBook for virtual speakers capable of recreating sounds from anywhere in the house, making users feel the sound comes from a different location than loudspeakers.It's a virtual acoustic system that works using "crosstalk cancelling" technology, according to a report in 9to5Mac, which is a similar technique to the noise cancelation found in Apple AirPods Pro.
Crosstalk refers to the sound waves from the left and right channels of a speaker that reach the ears.The result is to allow "spatial signals" to include audio signals that allow a sound to be essentially placed in a room. The U.S. Patent and Trademark Office granted Apple a patent on Crosstalk technology that could bring in the future new, more immersive audio applications. Initially, the tech giant filed the patent in 2018. Digital acoustics audio signal processing can significantly improve the feeling of being there, a movie, a sport, or a video game. The earlier Apple patent for built-in MacBook speakers places headphones in the place of Augmented Reality (AR) as a business tool for better conference calls. Even if they are not physically present, the AR headphone patent will allow you to hear where people are in a room.
