Active noise cancellation (ANC) is a technology that reduces unwanted ambient sound by generating an inverted audio signal that cancels out incoming noise waves. Commonly used in headphones, microphones, and broadcast equipment, ANC uses microphones to detect background noise and produces anti-phase sound waves that destructively interfere with it, resulting in a quieter listening or recording environment. In live production contexts, ANC can improve audio clarity during on-location recording or commentary by minimizing HVAC hum, crowd noise, and other environmental interference.
