Editing Flanging (section)

==Artificial flanging==
In the 1970s, advances in [[solid-state (electronics)|solid-state]] electronics made flanging possible using [[integrated circuit]] technology. Solid-state flanging devices fall into two categories: analog and digital. The [[Eventide, Inc|Eventide]] Instant Flanger from 1975 is an early example of a studio device that was able to successfully simulate tape flanging using [[Bucket-brigade device|bucket-brigades]] to create the audio delay.<ref>{{cite web |title=50th Flashback #5: FL 201 Instant Flanger |url=https://www.eventideaudio.com/blog/aagnello/50th-flashback-5-fl-201-instant-flanger |website=Eventide Audio |access-date=20 May 2021}}</ref> The flanging effect in most newer digital flangers relies on [[digital signal processing|DSP]] technology. Flanging can also be accomplished using computer software.<ref>{{cite web|url=http://filmandgamecomposers.com/blog/products/review-softube-fix-flanger-and-doubler/|title=Music Software Review: Fix Flanger and Doubler by Softube|date=27 May 2016|work=filmandgamecomposers.com|access-date=17 April 2017}}</ref><ref>{{cite web|url=http://philippseifried.com/blog/2011/11/01/dynamic-audio-4-comb-filters-flangers-and-chorus-effects/|title=Realtime audio processing, part 4: Comb filters, Flangers and Chorus effects – a bit of theory - philippseifried.com|work=philippseifried.com|access-date=17 April 2017|archive-url=https://web.archive.org/web/20170418081038/http://philippseifried.com/blog/2011/11/01/dynamic-audio-4-comb-filters-flangers-and-chorus-effects/|archive-date=18 April 2017|url-status=dead}}</ref><ref>{{cite web|url=https://wiki.analog.com/resources/tools-software/sigmastudio/toolbox/adialgorithms/flanger|title=Flanger [Analog Devices Wiki]|work=analog.com|access-date=17 April 2017}}</ref><ref>{{cite web|url=https://www.bluecataudio.com/Products/Product_Flanger/|title=Blue Cat's Flanger - Classic Flanging Effect Audio Plug-in (VST, AU, RTAS, AAX, DirectX) (Freeware)|work=bluecataudio.com|access-date=17 April 2017}}</ref><ref>{{cite web|url=https://tal-software.com/products/tal-effects|title=TAL - Togu Audio Line: TAL-Effects|work=tal-software.com|access-date=17 April 2017}}</ref><ref>{{cite web|url=http://www.kvraudio.com/product/azurite-by-distorque|title=Azurite by Distorque - Chorus VST Plugin|work=kvraudio.com|access-date=17 April 2017}}</ref><ref>{{cite web|url=http://basicsynth.com/index.php?page=flangers|title=Software Synthesis|work=basicsynth.com|access-date=17 April 2017}}</ref>{{Excessive citations inline|date=May 2024}}

The original tape-flanging effect sounds a little different from electronic and software recreations.<ref>{{cite web|url=http://forum.cockos.com/showthread.php?t=145303|title=Authentic Tape Flanging in REAPER. - Cockos Incorporated Forums|work=cockos.com|access-date=17 April 2017}}</ref><ref>[[REAPER]]</ref> Not only is the tape-flanging signal time-delayed, but response characteristics at different frequencies of the tape and tape heads introduced [[Phase (waves)|phase]] shifts into the signals as well. 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.

==="Barber pole" flanging===
Also known as "infinite flanging", this sonic illusion is similar to the [[Shepard tone]] effect, and is equivalent to an auditory "[[barber pole]]".<ref>[http://www.cycleback.com/sonicbarber.html "The Sonic Barber Pole: Shepard's Scale".] at cycleback.com.</ref><ref>{{cite web|url=https://www.kvraudio.com/product/barberpole_flanger_by_christian_budde|title=Barberpole Flanger by Christian Budde - Modulation (Flanger / Phaser / Chorus / Tremolo) VST Plugin|work=kvraudio.com|access-date=17 April 2017}}</ref> The sweep of the flanged sound seems to move in only one direction ("up" or "down") infinitely, instead of sweeping back-and-forth. 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 effect is available on various hardware and software effect systems.<ref>{{cite web|url=http://www.olilarkin.co.uk/index.php?p=eseries |title=audio software by oli larkin |publisher=Olilarkin.co.uk |access-date=13 August 2012}}</ref>
