denoise
Clean audio signal
To denoise is to remove unwanted random variation from a signal, image, or recording.
In audio production, denoising eliminates hiss or hum from recordings.
In photography, it reduces the grainy speckles that appear in low-light images.
The term is technical but increasingly familiar as editing software puts denoising tools in everyday hands: I had to denoise the interview recording to hear what she said.
