BLEASS Flanger is a comprehensive flanging effect with a wide range of sonic possibilities thanks to 2 LFOS, 3 Stages of modulation and beat synchronization.

BLEASS Flanger is a rich sounding flanging effect offering a wide range of synchronised modulations which colours sound in a novel and unique way thanks to its complex algorithmic combinations.

There are three stages of modulation as well as two LFOs, combined offering great sonic versatility - from classic sine flanger sounds to crazy rhythmic modulations courtesy of its 6 different LFO shapes.

The ability to easily synchronize the flanging effect with the beat makes it ideal to bring subtle flanging variations while evolving harmoniously with a song’s dynamics.

Our customary interface design makes for a smooth and efficient UI with clear visual feedback, increasing the enjoyment and playability of sound designing.

As with other BLEASS plugins, BLEASS Flanger is very low on CPU usage and works in all compatible hosts.


INPUT stage:
- Low-shelf/High-pass input filter
- Input gain

LFO A stage: (This LFO modulates DELAY TIME)
- SYNC: sets LFO’s synchronization between BEAT SYNC and FREE SYNC
- RATE: sets LFO’s rate
- OFFSET: when BEAT SYNC mode is activated, sets LFO’s offset relatively to the beat
- SHAPE: select LFO’s shape between sine, triangle, sawtooth, inverted sawtooth, square and random
- PHASE: sets offset between the LFO’s two stereo channels
- DEPTH: sets LFO’s amount as a percentage of DELAY TIME’s value
- STEREO METER: represents LFO’s state

LFO B stage: (This LFO can modulate either DELAY TIME, DELAY FEEDBACK or DELAY WIDTH)
- SYNC: sets the LFO’s synchronization between BEAT and FREE
- RATE: sets the LFO’s rate
- OFFSET: if SYNC is set to BEAT, sets LFO’s offset relatively to the beat
- SHAPE: select LFO’s shape between sine, triangle, sawtooth, inverted sawtooth, square and random
- PHASE: sets offset between LFO’s two channels
- DESTINATION: sets the LFO’s destination between DELAY TIME, FEEDBACK and WIDTH
- DEPTH: sets LFO’s amount as a percentage of DESTINATION’s value
- METER: represents LFO’s state (depending on the selected modulation destination)

ENVELOPE FOLLOWER stage: (modulates DELAY TIME depending on the input signal’s level)
- AMOUNT: sets the amount of modulation as a percentage of DELAY TIME’s value
- ATTACK: sets the attack of the follower
- RELEASE: sets the release of the follower

DELAY stage:
- TIME: sets average delay time
- FEEDBACK: sets average delay feedback
- WIDTH: sets delay time’s difference between both channels (and average delay time when width is modulated by LFO B)

MIX stage:
- POLARITY: if set to “+“, wet signal is added to the dry signal, if set to “-“, wet signal is subtracted to the dry signal
- DRY/WET: sets the amount of wet signal added (or subtracted) to the dry signal

* PLEASE NOTE: this is an Audio Unit Effect plugin (AUv3) which requires a compatible host such as AUM, Audiobus, GarageBand, Cubasis, BM3 and Auria. You can also use the BLEASS Flanger as a standalone app using headphones, a mic or an external sound card. *

Faith in flanging again

As a guitar player I was reluctant to purchase BlEASS Flanger. To me a flanger was a small box with three knobs, and they didn’t always sound that great. I own many other BLEASS products and I heard good things about their flanger so I took the plunge, and I was disappointed. The moment I loaded it and pressed the keys on one of my favorite synths I was impressed. It sounds amazing! I dove in and started tweaking some of the settings which allow users to create numerous sounds and presets of their own. Then I took it a step further and started modulating some of it’s other setting in AUM with an LFO. I look forward to using BLEASS Flanger on some film score projects. Get it! And leave a review.

Bleass Never Let’s Me Down

I have almost every BLEASS app, and I’m happy with each and every purchase. One of the best gui’s in the iOS game. Another winner with the flanger. Great on pads, organs, strings, or whatever really. I continue to use their apps on a daily basis, they are fairly priced, good quality, and easy to understand. Flanger sounds great, they all do. I know this is an individual app review that has somewhat turned into a BLEASS rant but I’ve been doing iOS music awhile and BLEASS is one of the best developers. There’s some good ones out there, but Bleass is clearly up there. 5 Stars.

GreAt flanger! Glad it can be so slow can it be even slower?

Beat sync to 64 or even 128/1 🙏🏽 love bleass ❤️
