Fog Convolver by AudioThing

Creative Convolution Processor

Fog Convolver is a modern take on convolution reverb that treats impulse responses as raw material rather than static snapshots of spaces. While it can recreate realistic rooms and environments with high fidelity, its real strength lies in transforming impulses into evolving, expressive sound-shaping elements.

Unlike classic convolution reverbs that rely on a single impulse response, Fog Convolver 2 is built around a dual-IR engine. Two impulse responses can be loaded simultaneously and combined in several routing configurations, allowing complex interactions between spaces, devices, textures, or abstract sound sources. This opens up possibilities ranging from natural stereo ambience to experimental and otherworldly effects.

Beyond Traditional Convolution

Fog Convolver 2 expands convolution with modulation, filtering, and dynamics processing. Each impulse response can be animated using LFOs, shaped with filters, and refined with equalization, making the reverb react and evolve over time. This movement helps avoid the static feel often associated with convolution-based effects.

Additional effects such as chorus, phaser, compression, and waveshaping can be applied within the plugin, turning Fog Convolver 2 into a complete spatial and tonal processor rather than just a reverb. These tools encourage creative experimentation and allow the effect to become an integral part of the sound rather than a finishing touch.

Spaces, Devices, and the Unusual

Fog Convolver 2 includes a broad and eclectic collection of impulse responses. These range from real acoustic spaces and classic hardware to organic materials, test equipment, and unconventional sound sources. The result is a library that supports both realistic spatial modeling and highly experimental sound design.

For deeper exploration, the built-in space simulator allows users to generate impulse responses from virtual rooms. By adjusting dimensions, materials, and source placement, entirely new acoustic environments can be created. An impulse generator further extends this concept, offering a more synthetic approach to crafting custom impulses.

Flexible Stereo and Routing Options

The plugin supports multiple routing modes, including true stereo processing, making it possible to preserve detailed spatial information or deliberately exaggerate stereo width. Using unrelated impulse responses on the left and right channels can result in rich, asymmetrical spaces that feel alive and immersive.

This routing flexibility makes Fog Convolver 2 suitable for everything from subtle depth enhancement to radical spatial manipulation. It can function as a realistic reverb, a creative effect, or even a tone-shaping processor driven by impulse responses.

Designed for Creative Workflows

Fog Convolver 2 is designed to integrate smoothly into modern production environments. Drag-and-drop loading of impulse responses, snapshot recall, and automation-friendly controls make it easy to experiment without breaking creative flow. Presets and snapshots allow complex setups to be recalled or morphed over time.

Whether used for mixing, cinematic sound design, ambient music, or experimental production, Fog Convolver 2 offers a powerful and flexible approach to convolution. It redefines what a convolution reverb can be, transforming spaces, textures, and impulses into dynamic creative tools.
