Under the hood

Incarnation of an iconic stomp box you will surely appreciate

In bringing the classic stomp box back to life, we’ve created a must-have effect plugin that will appeal not only to performing guitarists, but to instrumentalists and producers of virtually any genre: whether it’s rock guitar riffs or melodic synth lines you’re into, you’ll find that the extreme attention to sonic detail coupled with the flexibility afforded by modern technology in Antresol make it the perfect example of what a flanger should be in the modern era. The original, conceived in the mid-70s, quickly became a benchmark for flanger-type effects by offering a uniquely rich character defined by luxuriously harmonious interacting resonances, and has been heard ever since on countless classic recordings. That’s why D16 couldn’t resist the opportunity to resurrect the soul of this classic in a thoroughly modern incarnation with Antresol, our newest effect in the SilverLine Collection!

The key element around which Antresol is designed, an analog BBD integrated circuit, proved to offer some unique challenges for a digital emulation of this type. In particular, the feedback parameter showed some weaknesses in the form of improper shapes of emerging peaks and notches in the frequency response, forcing us back to the drawing board. After much R&D, our Eureka moment came in the form of a much-refined BBD emulation using quasi-analog signal representation throughout, guaranteeing behavior much more akin to the original, physical circuit. While a bit chaotic, it includes all the benefits and subtleties the analog domain can offer—unlike a deterministic, classically digital algorithm—and all this without any unwanted artifacts such as aliasing (something we always take great pains to minimize)… and all with the rock-solid stability only digital can offer!

True BBD Emulation

An exceptionally accurate emulation of an impulse-controlled, solid-state analog delay line (a Bucket Brigade Device) is responsible for the impeccable sonic characteristics found in Antresol. Effects based on high-quality BBD emulations stand out with remarkable, even seductive warmth, and we have no doubt that the tremendous success of D16’s first foray into BBD delay line emulation, the chorus plugin Syntorus, has been directly attributable to this approach.

Stereo LFO

Fully controllable LFO (with adjustable phase and rate sync to a host application’s tempo); the ability to delink the stereo channels and control the most important parameters independently for Left and Right (or Mid/Side, depending on selected mode).

Mistress mode

Enable Mistress mode and allow Antresol to take control over mixing and feedback get instant that distinctive sound, the same as the classic flanger.

M/S Mode

Switch between L/R or M/S processing modes and use Channel X-Fade knob to shape stereo sound stage to you desire.

Over the years I've owned and used many flangers, from hardware units to guitar pedals and plugins. Antresol is without a doubt the best sounding plugin flanger I've ever used.

David Guetta

These plugins sound amazing, some are secret weapons in my latest productions. A must have in your tools box, big up to the D16 Team for this great work !!!

Zardonic

Every single modulation effect I've found out there never sounds like what I imagine they should sound like. D16 builds plugins that sound like they should.
