01Overview

BLEASS Phaser is built around the classic phaser effect, which sweeps notches through the spectrum by combining a processed signal with the original. The developer describes it as an all-encompassing phasing effect, covering everything from resonant swirls to wide atmospheric stereo sounds. A spectrum display shows the estimated notch positions, and touching it adjusts the center frequency directly. The plugin is suited to synthesizers, guitars, basses and vocals.

Phaser Stage and Sound Shaping

The phaser stage sets the number of all-pass filters, which can range from 1 to 24. Each added filter creates a new notch in the signal's spectrum. The Frequency control sets the center frequency of the phaser, and Spread changes the spacing between notches by adjusting the Q factor of the filters.

Feedback reinjects part of the processed signal into the filter chain, and it can be set to negative values. Feedback Color applies a low-pass filter to the feedback path, which shapes how bright or dark the resonance sounds.

Frequency and Spread LFOs for Movement

BLEASS Phaser includes two sine LFOs, one for the center frequency and one for the spread parameter. Each LFO can sync to the host tempo in Beat mode or run freely in Hertz. Shape morphs between sine and triangle, Rate sets the speed, and Amount sets the modulation depth.

The Phase control sets the phase offset between left and right channels, which is the main tool for creating stereo motion. Together, the two LFOs allow the notch pattern to move in several ways at once.
