Beamforming is powered by digital signal processing as well as two concepts known as constructive and destructive. Audio beamforming is a research topic.
Here, multiple speakers, or an array of speakers, will play a crucial role. The main focus of audio-beamforming is to focus the strong audio signal in a particular direction or direction of the listener. For example, you want to enjoy a football match at night. But someone is not interested in the same room. Then you can enjoy the football match with a good sound without disturbing others. Here, the DSP audio signal processing tool will allow the sound to travel in a particular direction while canceling or minimizing the sound in the other direction for the desired audience's direction; it will work at the construction of soundwave mode while destruction on the other sides.
This technique may be very advanced in the future, using artificial technology or raytracing techniques to track the desired user and canceling the noise or interferences in this direction greatly compared to other directions.
