释义 | > as lemmastube saturation 15. A softly distorted and compressed quality imparted to a sound when the voltage of its audio signal exceeds the maximum at which it can be faithfully reproduced by a circuit, esp.: (a) that which occurs when sound is recorded onto magnetic tape at an amplitude that causes the tape to approach or exceed the point of magnetic saturation (more fully, tape saturation); (b) that which occurs when an amplifier employing thermionic valves is overdriven (more fully, tube saturation, valve saturation). In later use also: such a quality deliberately imparted to a sound using a device or software designed specifically for that purpose.Saturation is often thought to have a pleasing musical quality that adds presence and warmth to a sound, and is frequently employed in some genres of music for that purpose.Saturation occurring in an overdriven amplifier is not necessarily produced by saturation ( 12b(a)) of the valves. For example, saturation in this sense can instead be the result of current flowing from the grid of a valve into the input circuit. ΚΠ 1981 S. Keene Pract. Techniques for Recording Engineer (ed. 2) 59 Tape saturation is one kind of tape distortion. 2003 P. Prown & L. Sharken Gear Secrets of Guitar Legends 41 He [sc. Van Halen] ran the amp's controls cranked to the max, often using a Variac to manipulate the power so that the tubes would run much hotter than usual—a practice that enhances the amp's warmth and saturation, but shortens the life span of the power tubes. 2006 FutureMusic July 56/4 If you're looking for distortion, it's here—from mild valve saturation to over-the-top fuzzed-out madness. 2013 B. K. Shepard Redefining Sound viii. 189 Engineers frequently use saturation to warm up a sound, or to give it an ‘analog’ quality. < as lemmas |
