Sinevibes has released Whirl, an Audio Unit plugin for creating "barber-pole" phaser effects – with spectrum sweeps that go upwards or downwards in a seemingly endless fashion. It includes two different modes: first is a classic phaser based on the Bode frequency shifter that creates dramatic, wide-range spectrum swirls. Second mode is a barber-pole all-pass phaser which uses three sound layers coupled with six modulation oscillators, intended to produce a more full-bodied effect with distinct resonant peaks.
Both phasers in Whirl employ "through-zero frequency" modulation designed for silky smooth transition between upwards and downwards sweeps, plus they can have negative feedback for a artificial character. This plug-in can work on electric piano, synth strings and pads, electric guitar – but can also go into psychedelic stereo-widening or slowly morphing, hypnotic ambient drones.
Whirl is designed to have a clean and intuitive user interface. It features color-coded graphics for consistency with other plugins in their collection and calibrated contrast for optimal visibility in most lighting conditions. The interface supports retina resolution and also uses GPU-accelerated rendering, without impairing audio processing.
- Barber-pole Bode phaser with positive/negative feedback.
- Barber-pole all-pass phaser with 4, 5, 6, 7 or 8 stages, positive/negative feedback.
- Through-zero frequency modulation design for seamless transitions between upwards and downwards spectrum sweeps.
- Variable modulation phase offset for stereo widening or full spectrum inversion between the channels.
Price: $29. Whirl can also be purchased as part of Creative Collection and Complete Collection bundles with discounts of up to 70%.
