01Overview

Whirl approaches phasing differently from a conventional phaser. Its engine is based on a Bode frequency shifter model with a feedback line, producing peaks and notches that seem to move endlessly in one direction or the other. Up to three fully synchronized stages let you choose between a gentle effect and a dramatic one. At its most extreme settings, the plugin can take on a deeply resonant, filter-like character.

Sound Engine and Character

Sinevibes describes the sweep as bipolar, so the motion can move downward, switch to upward, and return without an audible seam. Each sweep morphs smoothly into the next, which is the core of the barber-pole effect.

The number of stages sets the intensity. With one stage the effect stays subtle, while three stages push it further. At extreme settings, Whirl suppresses and accentuates different harmonics, which gives it a resonant, filtered quality. A variable stereo phase offset adds width control, and the plugin supports mono to mono, mono to stereo and stereo to stereo configurations.

Controls, Interface and Workflow

Lag filters on all continuous parameters keep adjustments smooth and free of clicks. Parameter names, value mappings and units are consistent across the graphical interface and host automation, which makes automating sweeps straightforward.

The interface uses colour-coded graphics that match other Sinevibes plugins. It supports retina resolution, GPU-accelerated rendering and window scaling up to 200%. Built-in preset management is included.
