Signal routing refers to the process of directing signals from one point to another within a system, such as in telecommunications or audio engineering. It involves determining the best path for signals to travel, ensuring they reach their intended destination without interference or loss of quality. In audio systems, for example, signal routing allows sound from microphones or instruments to be sent to mixers, amplifiers, or speakers. This process is crucial for achieving clear sound and effective communication in various applications, including live performances and broadcasting. Proper signal routing enhances overall system performance and user experience.
