Sinevibes has introduced Whirl, an macOS AU plugin, designed to create ‘barber-pole’ phaser effects., that go endlessly upwards or downwards.

It includes two distinctly different modes:

• First is a classic phaser based on the Bode frequency shifter that creates dramatic, wide-range spectrum swirls.
• Second is a barber-pole all-pass phaser, which uses three sound layers, coupled with six modulation oscillators, producing a much more full-bodied effect with distinct resonant peaks.

Both phasers in Whirl employ “through-zero frequency” modulation design for smooth transition between upwards and downwards sweeps. They can also have negative feedback for a more unusual, artificial character.

Features:

• 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.

Pricing and Availability:

Whirl is available now for US $29.
