noise filter
Removes unwanted sound
A noise filter is a device or process that removes unwanted signals from audio, images, or data.
In audio equipment, noise filters reduce hiss, hum, or static.
In photography and video, they smooth out visual grain.
Email services use noise filters to screen spam.
The term applies broadly to anything that separates meaningful information from interference: The algorithm acts as a noise filter for the raw data.
