Whirl is a barber-pole phaser from Sinevibes based on a Bode frequency shifter, with peaks and notches that seem to move endlessly up or down.

What it does
Whirl is a barber-pole phaser: its sweep seems to rise or fall forever. Instead of a standard all-pass phaser it uses a Bode frequency shifter model, so the peaks and notches keep moving in one direction, each sweep morphing smoothly into the next, "like an audible illusion."
- Phaser engine: a Bode frequency shifter with up to three sequential stages and progressive feedback, which turns into deeply resonant filtering at extreme settings.
- Mode: sets how many phaser stages are active, from a gentler single stage to the full three-stage sound.
- Frequency and sync: the sweep speed and direction is set in Hz or as a fraction of host tempo, from 1/16 note up to 16 bars, locked to the transport.
- Stereo: a bipolar stereo phase offset, so the left and right sweeps can move against each other across the stereo field.
- Smoothing: lag filters on the continuous controls, so you can adjust and automate them without clicks.
- Channels and interface: mono to mono, mono to stereo and stereo to stereo, built-in preset management, and window scaling up to 200%.
A demo version is available, and v2 is a free upgrade for owners of the first version. Version 2 added the tempo sync and the bipolar stereo control.

When to use it
Whirl is the pick when you want one specific effect: a phaser sweep that never turns around. Unlike Soundtoys PhaseMistress, which models classic back-and-forth phasers with many styles and tone options, Whirl does one job with a small set of controls and costs much less. Compared with Eventide Instant Flanger Mk II or Soundtoys MicroShift it is more about constant motion than thickening or doubling. Its tempo sync, from a sixteenth note to 16 bars, makes it practical for rises and falls that line up with a song section.
- Best for: endless rising or falling sweeps on pads, guitars and drum loops, tension-building transitions, and resonant filter-like movement.
- Genres: electronic, ambient, psychedelic rock and experimental music.
- Look elsewhere if: you want a vintage-style phaser with a classic back-and-forth sweep; PhaseMistress fits better. For full rhythmic modulation shaping, ShaperBox 3 covers far more.
- Tip: use it sparingly, as Sinesquares suggests, on a few key moments rather than across a whole track, so the effect keeps its surprise.
What producers say
Coverage is light; the writers who discuss Whirl like its distinctive sound and simple, performance-friendly design.
- Sinesquares found it creates a recognisable sound and works both as a resonant filter sweep and as a regular phaser, but noted phasers are "a bit old-fashioned" and best used sparingly.
- CDM (Peter Kirn, 2023) called the v2 tempo sync "huge" and praised the developer's simplified, performance-friendly approach, suggesting it alongside other frequency-shifter effects.
