Eternal is a barber-pole flanger. Unlike a traditional flanger which has its tone repeatedly go up and down, a barber-pole flanger goes upwards or downwards in a seemingly endless fashion.

To accomplish this unique effect, Eternal employs a thoroughly calibrated low-frequency oscillator with six output signals which modulate and crossfade three flangers – and they do this in a very special way.

Since these oscillators have a “through-zero phase” design, Eternal can go from downwards to upwards motion and back completely seamlessly.

With two distinct timbres available thanks to positive or negative feedback, this plugin produces a wide variety of delicious spectrum sweeps – plus unusual chorus, pitch shift, and stereo widening effects.
