Intelligent Spectral Saturation

Spectral
Saturator.

Available for macOS • Windows version planned

A boutique saturation processor that shapes harmonics inside the spectrum, so warmth, density and presence land exactly where the music needs them.

Built for macOS producers who want saturation that feels musical, modern and controlled: nine modes, spectral targeting, transient protection, density processing, A/B compare, user presets and a live spectrum view.

AU, VST3 and Standalone for macOS only. Version v1.4.1. Windows version planned.

Watch Spectral Saturator shape the spectrum.

A short walkthrough of the modes, spectral targeting and the live spectrum view inside the real plugin.

What It Does

Not just louder. More intentional.

Spectral Saturator analyzes the signal with a high-resolution STFT engine and applies level-aware harmonic shaping per frequency bin. The result is saturation that can be broad, targeted, subtle or vivid without smearing the whole mix.

01

Spectral Processing

Frequency-bin aware saturation reacts to the spectral envelope instead of treating the entire signal as one block.

02

Harmonic Enhancement

Even and odd harmonic control lets you move from round second-harmonic warmth to sharper odd-harmonic bite.

03

Density Processing

Add body and perceived sustain through upward spectral density without turning every transient into mush.

04

Spectral Targeting

Five musical bands let you push lows, low mids, mids, high mids and highs independently.

05

Transient Preserve

Flux-aware transient protection reduces drive and density during attacks, keeping punch intact.

06

Premium Workflow

Factory presets, user presets, A/B compare, Mix Lock, Output Lock and a resizable interface support fast decisions.

Nine Saturation Modes

Choose the character before you turn the knob.

Each mode changes the spectral emphasis, harmonic bias, density behavior and rolloff, so the Drive control feels like a musical instrument instead of a generic distortion amount.

Warm

Round, darker, low-focused saturation with soft even harmonics for weight and glue.

Tube

Present second-harmonic tone with living mids and smooth brightness.

Tape

Darker cohesion, density and soft compression-like glue for drums, buses and synths.

Transformer

Harder mid-forward punch with odd-harmonic bite and a more aggressive edge.

Spectral

The signature mode: resonance-aware sheen, rich harmonics and polished spectral cohesion.

Focus

Emphasizes resonant musical energy so important notes speak without thinning the source.

Air

Silky high-frequency lift for expensive top end, presence and breath.

Density

Body, sustain and fill from stronger upward spectral density processing.

Exciter

Open clarity and harmonic presence for forward detail and modern shine.

Why Spectral

Classic saturation feel. Modern control.

Traditional saturators often add the same broad character to the entire source. Spectral Saturator lets you decide where the harmonic energy appears, how density behaves, and how much of the dry signal stays locked to the mix.

FAQ

Fast answers before checkout.

Which formats are included?

AU, VST3 and Standalone for macOS are included in the customer ZIP package.

Is there a Windows version?

No. Spectral Saturator is currently available for macOS only. Windows support is planned for a future version, but it is not included in this launch purchase.

Does it work in Ableton Live and Logic Pro?

Yes. Use the AU or VST3 in Ableton Live on macOS, and the AU in Logic Pro.

Is it a normal distortion plugin?

No. It is a spectral saturation processor that shapes harmonic energy with frequency-aware analysis and targeting.

Can I save my own presets?

Yes. User presets are saved on disk under Application Support and appear separately from the factory presets.

What if macOS blocks the app?

The Installation Guide includes Gatekeeper instructions and plugin scan troubleshooting.
