Sonicircuit Stereo Flanger is an effect plugin that creates a mixing of two identical signals together, one signal delayed by a small and gradually changing period, causing a 'phase shift' between the two signals. The length of this pause is gradually varied over time resulting in a 'sweeping' effect, delivering from subtle nuances to extreme jet engine taking off.

Primarily intended for use with guitar, vocals and synths, this virtual effects unit is versatile and intuitive to create new and unique textures.


  • A vast array of modulated tones that includes classic flanger as well as futuristic and chunky swirling sounds. From slow whooshes to rippling wobbles, from slow to fast space ray gun effects or from subtle textures to warped sound of a starting jet engine.
  • 24 Presets included. Ability to create new and interesting spacey, metallic or underwater quality to input signals.
  • Rhythmic flange effect, similar to an arpeggiator or sequencer, by emphasizing notes through rate and feedback highest settings and 'pulse' waveform active.
  • Stereo inputs and outputs, which is really suitable where ultra-wide flange sounds are needed.

Modulation Control:

Adds subtle to dramatic filtering effects and resonances to the sound, processing random "shifts" and "sweeps" in the frequency spectrum of original signal thus creating a sweeping, whooshing filter effect with a metallic, ringing sound:

  • Rate: Defines the frequency or speed of the oscillator. Turn the knob clockwise to increase the rate or counterclockwise to decrease the rate.
  • Feedback (Resonance, Regen): Determines the amount of the effect signal that is routed back into the input. This can change the tonal color and/or make the sweeping effect more pronounced. Higher settings yield a more dramatic effect. Many interesting tonalities such as bell tones, resonant pipes and robot voices sounds can be produced using high feedback values. Turn the knob clockwise to increase the rate or counterclockwise to decrease the regeneration.
  • Phase Modulation: Shifts the phase modulation. Spatial spread of the sound.
  • Waveform Combo Box: Shape of the modulating signal. A drop-down list to select different wave shapes: sine, saw, ramp, triangle and pulse plus white or pink noise.
  • Pulse Width Modulation: If the 'Pulse' waveform is selected, it control allows to set the 'Width' of rectangular pulse.

Audio Control: :

  • Dry/Wet Control (Mixer): Determines the balance between dry (unprocessed) and wet (processed) signals. Turn this knob clockwise for more effect or counterclockwise for less effect.

Preset Manager:

  • Browser to load and save presets and banks, enabling to export to *.fxp (VST2 Preset), *.fxb (VST2 Bank), *.vstpreset (VST3 Preset), *.aupreset (Audio Unit Preset) plus two generic formats (plain text): the *.xmlpreset (XML Preset) and the *.xmlbank (XML Bank), providing cross-platform presets/banks.
