Blue Cat's Phaser - Analog Modeled Phasing Effect Plug-in (VST, AU, VST3, AAX) (Freeware)

Modeled after vintage analog phaser circuits, Blue Cat's Phaser reproduces this old vintage phasing effect that you can find on so many recordings, but with the precision of modern digital processing techniques.

You can choose to apply up to 32 phasing stages, pushing the model to its limits, or create a subtle phasing effect with wet and feedback parameters set to a few percents.

You can also control the phase of the signal in the wet and feedback paths, which extends the possibilities of the original model.

On the stereo version, the additional "spread" control lets you obtain deep stereo widening phasing effects as well.

Main Features

  • Multi-stage analog-style phaser effect.
  • Up to 32 phasing stages.
  • Stereo spread control.
