Beamforming is a signal processing technique used in wireless communication to direct the transmission or reception of signals in specific directions. By using multiple antennas, it can focus the signal towards a particular user or device, improving the quality and range of the communication. This targeted approach reduces interference and enhances overall performance. In audio technology, beamforming is used to capture sound from a specific direction while minimizing noise from other sources. Microphones equipped with this technology can isolate voices in crowded environments, making it useful for applications like video conferencing and smart speakers.
