==="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>
