What Antresol does
The plugin is built around a true emulation of a BBD (bucket-brigade device) analogue delay line, the solid-state chip stage that gave classic flangers their character. The developer describes the emulation as impulse-controlled, and the plugin offers a total control set over the delay path. Each stereo channel can take its own independent parameter settings, and L/R and M/S stereo processing modes are selectable. A Mistress mode is included, in which the whole unit works the same as a classic flanger.
The LFO can be synchronized to the host application, and three different LFO-to-BBD clock curves shape how the sweep tracks the delay clock. The GUI comes in two alternative sizes, MIDI-learn is available throughout the interface, and internal processing runs at 64-bit. The plugin is distributed as VST3, VST2, AU, AAX and Standalone for Windows and macOS, and a trial is available; the Windows build lists Windows 7 and the macOS build lists macOS 10.13 as minimum systems.
Key features
- BBD delay emulation. The delay line is modeled on a bucket-brigade device, and the developer lists the emulation as a true analogue delay line in the impulse-controlled, solid-state category.
- Per-channel parameters. An optional mode lets each stereo channel carry independent parameter values instead of sharing one set across both sides.
- Stereo processing modes. L/R and M/S stereo processing modes can be selected, changing how the left and right signals are handled before the flanger stage.
- Mistress mode. In Mistress mode the whole unit works the same as a classic flanger, giving a fixed-behaviour alternative to the fully adjustable setup.
- Host-synced LFO. The LFO can be synchronized to the host application tempo, and three clock curves map the LFO onto the BBD clock in different shapes.
- Interface and control. Two alternative GUI sizes are offered, and MIDI-learn is available for the controls throughout the interface.
Use cases
- Stompbox-style flanging. The Mistress mode recreates the behaviour of a classic flanger stompbox, which suits sessions that need the fixed sweep of the original unit.
- Per-channel stereo sweeps. Independent channel parameters and M/S processing let a producer shape the left and right flanging separately on a stereo source.
Compatibility
Antresol is distributed as VST3, VST2, AU, AAX and Standalone for Windows and macOS (64-bit), with native Apple Silicon support listed. The minimum systems are Windows 7 and macOS 10.13, the RAM requirement is 8 GB, and a trial version is available.
Who it is for
Producers and mix engineers who want a BBD-style flanger with host-synced modulation and a fixed classic mode alongside fully adjustable stereo control.
