A noise print is part of a technique used in noise reduction. A noise print is commonly used in audio mastering to reduce the effects of unwanted noise from a piece of audio. In this case, the noise print would be a recording of the ambient noise in the room, which is then used to set multiple expanders, effectively 'gating out' those frequencies whilst the signal level in that band is lower than that in the noise print. Many plugins for Studio software can be used to apply noise reduction in this way.
Noise reduction usually results in unwanted artifacts, sometimes referred to as "twittering" or "birdies". Different algorithms for noise reduction control these artifacts with varying levels of success.
Famous quotes containing the words noise and/or print:
“For twenty-five centuries, Western knowledge has tried to look upon the world. It has failed to understand that the world is not for the beholding. It is for hearing. It is not legible, but audible. Our science has always desired to monitor, measure, abstract, and castrate meaning, forgetting that life is full of noise and that death alone is silent: work noise, noise of man, and noise of beast. Noise bought, sold, or prohibited. Nothing essential happens in the absence of noise.”
—Jacques Attali (b. 1943)
“For a long time I was reporter to a journal, of no very wide circulation, whose editor has never yet seen fit to print the bulk of my contributions, and, as is too common with writers, I got only my labor for my pains. However, in this case my pains were their own reward.”
—Henry David Thoreau (1817–1862)
