Topics similar to or like Flanging. Also known as "infinite flanging", this sonic illusion is similar to the Shepard tone effect, and is equivalent to an auditory "barber pole". Flanges are used to connect pipes with each other, connect pipes to flanged valves, connect pipes to flanged fittings, connect pipes to flanged piping specialty items such as strainers and to isolate piping sections using a blind flange.[1]. The product range includes SORF, SOFF, BLRF, BLFF, WNRF (XS, XXS, STD & Schedule 20, 40, 80), WNFF (XS, XXS, STD & Schedule 20, 40, 80), SWRF (XS & STD), SWFF (XS & STD), Threaded RF, Threaded FF & LJ, with sizes from 1/2" to 16". Flanging is an audio effect produced by mixing two identical signals together, one signal delayed by a small and gradually changing period, usually smaller than 20 milliseconds.This produces a swept comb filter effect: peaks and notches are produced in the resulting frequency spectrum, related to each other in a linear harmonic series. A blind flange is a plate for covering or closing the end of a pipe. This produces a swept comb filter effect: peaks and notches are produced in the resultant frequency spectrum, related to each other in a linear harmonic series. The history of the flanging effect. The forging process is ideally suited to many part applications; however, some buyers may be unaware of the exclusive benefits available only from this form of metal forming. In 1968, the record producer for the Litter, Warren Kendrick, devised a method to precisely control flanging by placing two 15 IPS (inches per second) stereo Ampex tape recorders side by side. Lennon asked George Martin to explain how ADT worked, and Martin answered with the nonsense explanation "Now listen, it's very simple. Flanging is a forming or bending operation that results in a 90-degree bending of the metal. Older recording hardware could suffer flanging as a side effect when recording long tracks. Unique pressure classes for piping can also be developed for a process plant or power generating station; these may be specific to the corporation, engineering procurement and construction (EPC) contractor, or the process plant owner. Tape flanging was not the province of a precise LFO, but rather a sort of sloppy process where tape would speed up or slow down past the zero point. These flanges are recognized by ASME Pipe Codes such as ASME B31.1 Power Piping, and ASME B31.3 Process Piping. We take the original image and we split it through a double vibrocated sploshing flange with double negative feedback". Flanging, on the other hand, uses a delay applied equally to the entire signal which is similar in principle to phasing except that the delay (and hence phase shift) is uniform across the entire sound. This stage is about minimizing and avoiding burrs, which can drive up the cost of your part and extend lead time. The original tape-flanging effect sounds a little different from electronic and software recreations. A similar "jet plane-like" effect occurs naturally in long distance shortwave radio music broadcasts. [2], These pressure classes also have differing pressure and temperature ratings for different materials. They are typically made from forged materials and have machined surfaces. listen to the tape flanging effect on the 1967 single. An Essex flange requires a hole to be drilled in the side of the tank. Although the word flange generally refers to the actual raised rim or lip of a fitting, many flanged plumbing fittings are themselves known as 'flanges': Common flanges used in plumbing are the Surrey flange or Danzey flange, York flange, Sussex flange and Essex flange. blanking, bending, flanging, and deep drawing, as well as more advanced forming applications like hot stamping, warm forming, sheet/tube hydroforming, and incremental sheet forming. "The Sonic Barber Pole: Shepard's Scale". Theoretically, the flange also remains in contact along its outer circumference at the flange faces for all allowable load levels that it is designed for. There is also a Warix flange which is the same as a York flange but the shower output is on the top of the flange and the vent on the side. The initial cost of the theoretical higher performance compact flange is inevitably higher than a regular flange due to the closer tolerances and significantly more sophisticated design and installation requirements. Varying the time delay causes these to sweep up and down the frequency spectrum. In this case the varying delays are caused by varying radio wave propagation times and multipath radio interference. When Revolver was released on 5 August 1966, almost every song had been subjected to flanging.[5]. The flanging effect is as an audio process which combines two audio signals. - Cockos Incorporated Forums". By pressing a finger on the flange of the other deck, the effect sweeps back in the other direction as the decks progress towards being in sync. The seal ring force is provided by the elastic stored energy in the stressed seal ring. The term "flanging" comes from one of the early methods of producing the effect. Flanging is created by putting the signal through a delay, which has its delay time slowly modulated from about 4 ms to 15ms, with a modulation cycle taking between 1/4 second and 10 seconds to complete. To allow easy functionality and interchangeability, these are designed to have standardised dimensions. While Shepard tones are created by generating a cascade of tones, fading in and out while sweeping the pitch either up or down, barber pole flanging uses a cascade of multiple delay lines, fading each one into the mix and fading it out as it sweeps to the delay time limit. The phase of the fed-back signal is sometimes inverted, producing another variation on the flanger sound. Blanking 3. The remaining tape-flanging characteristic that few processors emulate (I've only seen it in Virsyn's tape flanger) is the inertia of tape machines. Further, many of the flanges in each standard are divided into "pressure classes", allowing flanges to be capable of taking different pressure ratings. The ASME pressure classes for Flat-Face flanges are Class 125 and Class 250. The playback-head output from the two recorders is mixed to a third recorder. Flanging. It also provides easy access for cleaning, inspection or modification. A closet flange provides the mount for a toilet. As an audio effect, a listener hears a "drainpipe" or "swoosh" or "jet plane" sweeping effect as shifting sum-and-difference harmonics are created analogous to use of a variable notch filter. To the ear, flanging and phasing sound similar, yet they are recognizable as distinct colorations. Process acceleration by high-speed incremental hole flanging To increase the industrial relevance of incremental hole flanging, the process was accelerated based on the observation that the kinematics of incremental hole flanging require to perform a series of revolutions with superimposed or subsequent axial and radial feed. Thus, while the peaks and troughs of the comb filter are more or less in a linear harmonic series, there is a significant non-linear behaviour too, causing the timbre of tape-flanging to sound more like a combination of what came to be known as flanging and phasing. Sheet metal is metal formed by an industrial process into thin, flat pieces. Pipe flanges that are made to standards called out by ASME B16.5 or ASME B16.47, and MSS SP-44. Generally used for thin sheet metal processing. This results in constructive and destructive interference that varies with frequency, giving a series of peaks and troughs in the frequency response of the system. stretch flanging noun. Thus, this prevents corrosion of the flange faces, the stressed length of the bolts and the seal ring. As an audio effect, a listener hears a "drainpipe" or "swoosh" or "jet plane" sweeping effect as shifting sum-and-difference harmonics are created analogous to use of a variable notch filter. On "Mammy's Boogie" (1952) he used two disk recorders, one with a variable speed control. ASME B16.5 refers to nominal pipe sizes (NPS) from ½" to 24". In contrast, flanging relies on adding the signal to a uniform time-delayed copy of itself, which results in an output signal with peaks and troughs which are in a harmonic series. Most countries in Europe mainly install flanges according to standard DIN EN 1092-1 (forged Stainless or Steel Flanges). The flange faces are also made to standardized dimensions and are typically "flat face", "raised face", "tongue and groove", or "ring joint" styles, although other obscure styles are possible. Flanging is a time-based audio effect that occurs when two identical signals are mixed together, but with one signal time-delayed by a small and gradually changing amount, usually smaller than 20 milliseconds. ASME B16.5 covers flanges up to 24 inches size and up to pressure rating of Class 2500. (December 2009) (Learn how and when to remove this template message) Thus flanged wheels are wheels with a flange on one side to keep the wheels from running off the rails. Coin… However these classes do not correspond to maximum pressures in psi. Thinning hole-flanging or flanging refers to a deformation process that uses a smaller die gap to force the thickness of the vertical edge to become thinner and increase in height. The flanging is also called perforation, which is to draw a slightly larger hole on a smaller base hole and then tap on the hole. This produces a swept comb filter effect: peaks and notches are produced in the resulting frequency spectrum, related to each other in a linear harmonic series. In both phasing and flanging, the characteristics (phase response and time delay respectively) are generally varied in time, leading to an audible sweeping effect. Extending the comb analogy, flanging yields a comb filter with regularly spaced teeth, whereas phasing results in a comb filter with irregularly spaced teeth. Several different microwave RF flange types exist, such as CAR, CBR, OPC, PAR, PBJ, PBR, PDR, UAR, UBR, UDR, icp and UPX. an ASME flange will not mate against an ISO flange). According to the European form the seals are indicated by different form: Flanges in the rest of the world are manufactured according to the ISO standards for materials, pressure ratings, etc. In the USA, ANSI stopped publishing B16.5 in 1996, and the standard is ASME B16.5. When the breakline of the bend is greater than the developed trim line, the operation is referred to as stretch flanging; when the breakline is smaller than the developed trim line, the operation is called shrink flanging. Anagrams . Each specification further delineates flanges into pressure classes: 150, 300, 400, 600, 900, 1500 and 2500 for B16.5, and B16.47 delineates its flanges into pressure classes 75, 150, 300, 400, 600, 900. Diagram by Warren Kendrick – 'K-Tel Reissue CD 10002 (1991)', constructive and destructive interference, 'Listen to My Voice’: The Evocative Power of Vocal Staging in Recorded Rock Music and Other Forms of Vocal Expression, "Thru-Zero Flanger - Classic tape-flanging simulation", "Liquid by Audio Damage - Modulation (Flanger / Phaser / Chorus / Tremolo) VST Plugin and Audio Units Plugin", "Music Software Review: Fix Flanger and Doubler by Softube", "Realtime audio processing, part 4: Comb filters, Flangers and Chorus effects – a bit of theory - philippseifried.com", "Blue Cat's Flanger - Classic Flanging Effect Audio Plug-in (VST, AU, RTAS, AAX, DirectX) (Freeware)", "Azurite by Distorque - Chorus VST Plugin", "Authentic Tape Flanging in REAPER. B16.47 covers NPSs from 26" to 60". They are often used to ensure an even flow of water to showers. The first Beatles track to feature flanging was "Tomorrow Never Knows" from Revolver, which was recorded on 6 April 1966. The second signal is slightly delayed and therefore the combined signal produces a “swirling“ effect. A time-based audio effect produced when two identical signals are mixed together, but with one signal time-delayed by a small and gradually changing amount, usually smaller than 20 milliseconds. It is more apparent when it is applied to material with a rich harmonic content, and is most obvious when applied to a white noise or similar noise signal. A flange is an external or internal ridge, or rim (lip), for strength, as the flange of an iron beam such as an I-beam or a T-beam; or for attachment to another object, as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera; or for a flange of a rail car or tram wheel. If the frequency response of this effect is plotted on a graph, the trace resembles a comb, and so is called a comb filter. Townsend devised artificial double tracking or ADT. This course is beneficial for designers, engineers, and managers involved in new product development, stamping process engineering, The same configuration was employed during the playback/mixdown to a third recorder. As the Compact flange size increase it becomes relatively increasingly heavy and complex resulting in high procurement, installation and maintenance costs.

In the 1970s, advances in solid-state electronics made flanging possible using integrated circuit technology. For the musical project, see. As the weight of the tape built on one reel, the pressure on the capstans caused flanging in mixdown or dubbing.

Flanges are piping components bolted together using gasket in between two flanges as a sealing material. Commonly, flanging is referred to as having a "jet-plane-like" characteristic. Flanging is an audio process that combines two copies of the same signal , with the second delayed slightly, to produce a swirling effect. Despite subsequent claims over who originated flanging, Les Paul discovered the effect in the late 1940s and 1950s; however, he did most of his early phasing experiments with acetate disks on variable-speed record players.
