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:
“And its noise as the noise in a dream; and its depth as the roots
of the sea:”
—A.C. (Algernon Charles)
“As for the herd of newspapers and magazines, I do not chance to know an editor in the country who will deliberately print anything which he knows will ultimately and permanently reduce the number of his subscribers. They do not believe that it would be expedient. How then can they print truth?”
—Henry David Thoreau (1817–1862)
