ASH 2 is the next evolution of Acustica’s acclaimed mastering clipper, now redesigned as a single, unified plug-in for a faster and more direct workflow.
Built around a new generation of NOVA-derived processing, ASH 2 combines converter-inspired tone, model-specific saturation, harmonic enhancement, transient shaping, and advanced clipping behavior in one streamlined environment. The result is greater punch, density, and perceived loudness while preserving musicality and control.
Available in VST3, AAX, and AU formats for macOS and Windows.
The benchmark evolved
For years, ASH has been a trusted tool for engineers looking to increase loudness, control peaks, and add density without sacrificing the integrity of the mix.
ASH 2 takes that philosophy further by unifying the entire ASH ecosystem into a single plug-in while introducing new saturation technologies, deeper harmonic behavior, expanded monitoring, and entirely new clipping models.
The workflow is faster, the architecture is more complete, and the sonic palette is broader than ever before.
28 Emulations. Endless Possibilities.
ASH 2 includes 28 emulations organized into 10 classic and modern clipping families.
Derived from selected high-end converters, iconic hardware units, and custom circuits, each model combines its own clipping response with a dedicated NOVA-powered preamplification stage, delivering a unique balance of saturation, harmonic density, transient behavior, and tonal character.
From transparent mastering enhancement to aggressive loudness shaping, every emulation offers its own sonic identity, allowing ASH 2 to adapt equally well to tracks, stems, buses, mix bus processing, and final mastering duties.
Three Views. One Workflow.
ASH 2 includes three interface modes designed to match different workflows and visual preferences. Whether you prefer Acustica’s classic hardware-inspired look, a streamlined standard layout, or an extended view with deeper metering and controls, every mode provides access to the same processing engine and sonic capabilities. Choose the view that fits your workflow and stay focused on the sound.

Key Features
- Unified Workflow – All ASH versions merged into one fast and streamlined plug-in.
- 28 Emulations – Ten clipping families with distinct sonic personalities and workflows.
- NOVA Saturation – Combines Vectorial Volterra Kernels (V.V.K) with a neural processing stage to represent both low-level accuracy and nonlinear behavior.
- Advanced Clipping – From transparent peak control to aggressive loudness enhancement.
- Perceived Loudness – Increase punch and apparent volume without losing musicality.
- Final Master Control – Clipping, True Peak, LUFS, dither, and output management in one workflow.
- Factory Presets – Provides preset configurations as starting points for common mixing and mastering tasks.
About NOVA
NOVA, short for Neural Optimized Volterra Audio, is Acustica’s hybrid architecture combining our Vectorial Volterra Kernels-based technology with advanced neural audio modeling.
In ASH 2, NOVA powers the integrated dual preamp stage. It allows the plugin to preserve the tonal structure, frequency response, and phase behavior of the original hardware while reacting more naturally as the input level increases.
Rather than switching between separate models, NOVA combines both approaches simultaneously: the Volterra component helps maintain structural accuracy and tonal stability, while the neural component captures the more complex nonlinear behavior that emerges when the circuit is driven harder.
The result is an input-dependent harmonic response that moves smoothly from cleaner tonal shaping to richer saturation, while maintaining the musical balance of the of the original clipper design.
