Finn
FINN is a versatile all-in-one processor designed to bring modern analog sound into a fast, streamlined workflow. Combining curated analog color, tone shaping, flexible equalization, dynamics and stereo processing in a single environment, it integrates Acustica's latest-generation NOVA modeling technology to deliver complex nonlinear analog behavior within an immediate and flexible processor. From subtle mix-bus refinement to more creative processing on groups, stems and individual tracks, FINN is available in VST3, AAX and AU formats for macOS and Windows.
A Modern Approach to Analog Processing

FINN was created around a simple idea: bringing together some of the most effective approaches to analog processing in a single, focused environment. Rather than recreating one specific piece of hardware or building another complex vintage-style chain, its design draws from different analog circuits and processing philosophies, selected for the way they shape color, tone and dynamics.


These elements were then brought together into a more contemporary processing concept, where each stage contributes to the sound without adding unnecessary complexity. The result is a flexible processor built around immediacy, interaction and character, equally at home refining a full mix or taking individual tracks and stems in a more creative direction.

Key Features
Curated Analog Color

Solid State and Tube preamps deliver distinct tonal and harmonic characters.

NOVA Processing

NOVA modeling brings dynamic nonlinear analog behavior into FINN's processing.

Fast Tone Shaping

Resonant filters and Tilt EQ reshape weight, extension and tonal balance fast.

Flexible Analog EQ

Analog-derived responses combine musical character with continuous control over the shape of each curve.

9 Dynamic Behaviours

PEAK, RMS and Limiter modes shape how FINN reacts to dynamics and transients.

EUPHONIC Decorrelation

Introduces controlled L/R differences for a more organic, analog-like stereo character.
