Molecular Bytes AtomicReverb 2

The Evolution of Algorithmic Reverb

AtomicReverb 2 is a fully reimagined high-end algorithmic reverb plugin designed for VST, AAX, and Audio Units.

Every aspect of the sound engine has been refined, offering improved early reflections, new reverb tail models, tail attack, and dynamic behavior that responds more naturally than ever before.

Processing capabilities like smooth transitions during parameter changes, reverb hold for endless sustain, and mono frequency control in the low end give you unprecedented control.

Dynamic response has been enhanced with additional processing options such as ducking, emphasis and softening, allowing reverb to adapt intelligently to the input signal.

Rooms, Halls, Plates, and Beyond

With over 260 factory presets and more than 190 distinct early reflection signatures, Atomic Reverb 2 provides a broad sonic base that can be freely shaped in tone, size, diffusion, and color.

The rebuilt processing engine delivers highly realistic and musical reverb spaces ranging from subtle ambience to expansive cinematic depth.

The new 'Diffuse Room' tail type further expands the creative palette with a rich, airy texture perfect for modern productions.

Early reflections, extracted from real-world spaces, have always been a defining element of AtomicReverb - and in version 2, their detail and realism have been taken to a new level.

The tail section has been enhanced as well, supporting interesting absorption effects, complex modulations, gated tails and customized tail shaping that lets you sculpt the spatial behavior with precision.

This dramatically enhances the sonic range to produce sounds from subtle voice reverbs over impressive rooms to full and dense halls or even tubes, stages, plates or special FX.

A Unique Reverb Engine

Unlike many conventional reverb effects that focus primarily on tail design, atomicreverb 2 puts early reflections at the center of its spatial modeling approach.

These early reflections are the key to perceived room character, yet they’re often neglected or oversimplified. atomicreverb’s edge lies in the accurate recreation of real-world reflection patterns, carefully modeled after impulse responses – but entirely algorithmic and dynamic.

Tail design, too, goes beyond the expected. With three refined tail models, atomicreverb 2 offers distinct acoustic flavors:

Hard Room simulates spaces with strong, long-lasting reflections and clear geometric definition.

The all-new Diffuse Room spreads reflections rapidly into a soft, airy decay - ideal for modern mixes.

Full-Dense, an innovative concept, creates an ultra-smooth decay with no distinct reflections at all - a "perfect" reverb space that blends seamlessly into the sound.

No Resonances Allowed

AtomicReverb also continuously analyzes and corrects the reverberation response to prevent unwanted resonances - regardless of the room size.

The result is a pristine, undistorted spatial image that remains truthful to real-world acoustics unless intentionally shaped otherwise.

High Performance Meets Precision

At the heart of atomicreverb 2 is a sophisticated 64-bit internal architecture with optional 2x oversampling that ensures precision and sonic integrity across the entire signal path.

Each preset stores its own level of detail to optimize CPU usage, while the new processing engine allows for ultra-long, accurate tails - even beyond minutes.

Highly optimized code (and native ARM support on MacOS systems) delivers excellent performance, even in large projects.

Realistic, Not Static

Atomic Reverb 2 remains a fully dynamic algorithmic reverb – no convolution, no static IR data.

Every reverb tail is generated in real-time, shaped by complex modulation and frequency-depending energy decay to create unique, evolving reflections.

This approach not only delivers a more natural result, it also ensures that each instance of the plugin sounds slightly different - just like in the real world.

A Workflow You'll Enjoy

The all-new user interface combines clarity and speed, offering a powerful preset search with category counters, a streamlined previous/next preset navigation, and intuitive parameter displays such as reverb time and pre-delay now shown in host-synchronized musical values.

The peak meter can be adjusted for overflow sensitivity, and helpful tooltips can be enabled or hidden depending on your preference.

Reverb time is no longer set by percentage but directly in seconds, allowing for more precise and musically intuitive adjustments.

Everything You Expect, and More

Of course, all the essentials you'd expect from a reverb plugin are still here.

AtomicReverb 2 features a fully integrated 5-band EQ with real-time spectrum analyzer, and parameters like Dry/Wet, Gain, and Density can be locked to maintain consistency while browsing presets.

Preset management is enhanced through A/B comparison, undo/redo functionality, and easy XML-based sharing via the system clipboard.

Using the integrated MIDI-learn function, parameters can be assigned to MIDI controllers via your host-software.

Atomic Reverb 2 also supports an arbitrary scalable/resizable user-interface and two different skins.

Standalone Application (Windows)

For Windows-Systems a standalone application is included to use Atomic Reverb 2 directly as a reverb-effect through your audio-hardware.

An easy way to use it as an effect unit for your live-performance without a DAW!
