Antresol: BBD Flanger Plugin by D16 Group Free Download

D16 Group says Antresol's core is an emulation of an impulse-controlled, solid-state analogue delay line, known as a Bucket Brigade Device. The developer describes the sound as warm and highly musical, and says the emulation works in a quasi-analog signal representation rather than a purely deterministic digital algorithm.

The company also states that its frequency response comparison with the original Electric Mistress stompbox shows a close match, including at the upper end of the spectrum, where emulations often diverge. Output is described as ultra-low-aliasing.

Antresol offers the standard parameter knobs of the original unit along with deeper settings such as trimmer-level controls and the number of analogue memory cells in the BBD model. Mistress mode makes the whole unit behave like the classic flanger.

The LFO can sync to your host application's tempo and has adjustable phase and rate. Three different LFO-to-BBD clock curves are available. Stereo channels can be delinked, with selectable L/R or M/S processing modes, and MIDI learn works across the interface.

Antresol is aimed at guitarists, instrumentalists and producers working in most genres. The developer frames it as suitable for rock guitar riffs as well as melodic synth lines. Its deep parameter access makes it a fit for sound designers who want to shape a flanger beyond the presets of a fixed unit.
