noise reduction

noun

The process of removing unwanted disturbances (noise) from signals like audio, images, or video, using techniques such as spectral gating for audio to filter out constant hums (like hiss or fans) or active noise control (ANC) in headphones to create opposing sound waves, all aimed at improving clarity, reducing distortion, and focusing on desired content by isolating noise from the primary signal.
