After delivering 3 mastering FX plugins last week, 4Pockets have brought us 3 more audio units as a ‘modulation’ group. Included in this bundle are: Phaser, Flanger, and Vintage Vibe. Here’s what to expect from each of these.

The first is the stereo Analog Flanger plugin which can obviously be used as a plugin with your favourite DAW such as Cubasis, Auria, Meteor or GarageBand.

The Flanger is a modulation effect capable of creating a range of subtle chorus to extreme flanging effects.

Flanging is an audio effect produced by mixing two identical signals together, one signal delayed by a small and gradually changing period. This produces a sweeping comb filter effect with peaks and notches in the resulting frequency spectrum. The feedback control produces a resonance effect which further enhances the intensity of these peaks and troughs.

Next up is the Vintage Vibe, which is a modulation effect capable of creating a dopplar type effect like that of the Leslie speaker as well as various shimmering and stereo widening effects. This type of effect was traditionally used on electric organ and guitars in the late 70’s, pioneered by the likes of Hendrix and Pink Floyd.

The Analog Phaser is a modulation effect capable of creating a range of phasing similar to traditional analog effects of old. This effect is great for creating those 80’s inspired swirling filtering effects which were often applied to keyboard and guitars.

As per the other group, the mastering group, there’s a bundle too, which costs $11.99, where as the individual audio units cost $4.99 each. So not a bad deal at all.
