Whirl

Whirl is a barber-pole phaser effect plugin. 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.

Sound Engine:

• Barber-pole phaser based on Bode frequency shifter, with up to three sequential stages and progressive feedback.

• Variable bipolar stereo phase offset.
• Lag filters on all continuous parameters for smooth, click-free adjustment.
• Supports mono › mono, mono › stereo, and stereo › stereo channel configurations.

Graphic Interface:

• Color-coded graphic elements.
• Consistent name, mapping, value, and unit implemented for all parameters in both graphic user interface and host control/automation.
• Built-in preset management functions.
• Supports window size scaling up to 200%.

Supported Formats:

• AAX + AU + VST3 for macOS 10.9 or later (64-bit Intel and Apple Silicon).
