What it does

BLEASS Flanger is a delay-based flanger that takes the sound of classic flangers and adds more modulation: two LFOs, an envelope follower and beat sync. BLEASS sums it up as "2 LFOs, 3 stages of modulation and beat synchronization".

Input stage: input gain and a filter that switches between low shelf and high-pass, to shape what goes into the flanger.
LFO A: modulates the delay time, with free or beat-synced rate, offset, phase and depth, and six waveforms: sine, triangle, sawtooth, inverted sawtooth, square and random.
LFO B: a second LFO with the same controls and waveforms that can target delay time, feedback or stereo width.
Envelope follower: moves the delay time with the input level, with attack, release and amount controls.
Delay stage: time, feedback and width controls.
Mix stage: a polarity switch for additive or subtractive (negative) flanging, and a dry/wet balance.
CPU: BLEASS stresses that it is very light on CPU.

The current version is 1.3.0 (desktop). A trial with full features is available.

When to use it

BLEASS Flanger is the better pick for cheap, heavily modulated flanging: two LFOs with six shapes, a second LFO that can move feedback or width, and an envelope follower. Compared with Eventide's Instant Flanger Mk II, which is modelled on Eventide's own hardware flanger, it is less about one classic tape-style sound and more about building animated, synced sweeps. Unlike MicroShift, which is a subtle widener, it makes an obvious jet-like sweep, and it is narrower in scope than UberMod's multi-tap modulation delays. Its polarity switch gives both the hollow negative flange and the usual additive sound.

Best for: synced flanger sweeps and dynamic, envelope-driven flanging on synths, drums, guitars and vocals.
Genres: electronic music, rock, pop and psychedelia.
Look elsewhere if: you want a classic hardware flange sound (Instant Flanger Mk II) or a broader modulation multi-effect (UberMod).
