Whirl is a barber-pole phaser effect plugin for Mac. It is based on a Bode frequency shifter model with a feedback line, an algorithm which creates unique spectrum peaks and notches that move upwards or downwards in a seemingly endless fashion – with one spectrum sweep smoothly morphing into the next one, like an audible illusion. Whirl features up to three fully synchronized barber-pole phaser stages: this allows you to control how gentle or dramatic the effect is. At its most extreme settings, Whirl is capable of deeply resonant filtering: it almost individually suppresses and accentuates different frequency harmonics. By design, the spectrum sweep frequency is bipolar - and can go from downwards to upwards motion and back completely seamlessly.
