Barber-Pole Flanger

Eternal by Sinevibes is a barber-pole flanger effect. Unlike a traditional flanger which typically has its tone repeatedly go up and down, this is a flanger that goes upwards or downwards in a seemingly endless fashion. To accomplish this unique “barber-pole” effect, Eternal uses an array of three stereo flangers and six bespoke, thoroughly calibrated low-frequency oscillators. And since these oscillators have a “through-zero” design, it allows Eternal to seamlessly go from downwards to upwards motion and back at your fancy. With two distinct flanger tones thanks to positive or negative feedback, this plugin puts a whole arsenal of unique airy, bubbly and even psychedelic effects in your hands.

Eternal has an intuitive user interface wholly built with color-coded graphics and subtle animations. Together with carefully tuned parameters, this highly musical effect also gives you an enjoyable and inspiring user experience.
