noise reduction
Lessening unwanted audio
Noise reduction is the process of minimizing unwanted sound or signal interference.
In audio, it removes hiss, hum, or background noise from recordings: The software's noise reduction cleaned up the old tape.
In photography and video, it reduces visual grain caused by high ISO settings.
Noise-canceling headphones use active noise reduction to counter ambient sound with opposing frequencies.
