microphone array signal processing techniques

Microphone array signal processing involves using multiple microphones to capture sound signals and improve audio quality or extract specific sounds. Techniques like beamforming focus on dividing the sound environment into directions, allowing the system to "listen" more carefully to a target source (like a person's voice) while reducing background noise. Algorithms analyze the differences in sound signals arriving at different microphones to locate sound sources and enhance desired audio. These methods are essential in applications like conference calls, speech recognition, and noise reduction, enabling clearer communication and more accurate sound detection in complex environments.
