THE INTERFACE

Four views. One plugin.

FAT-X3 ships with layouts for every stage of a session — from the full spread of every band-strip control to a compact display that tucks into a busy template. Click through the screens below.

Main view

Every control, always visible.

Three band strips side-by-side with the full per-band chain — comp, distortion, widener, mid/side, filters — plus the shared display on the right. Here the display is on the FILTERS tab, showing the five parametric EQ curves and the pre/post routing row underneath.

SIGNAL FLOW

Everything in the right order.

A 24 dB/oct Linkwitz-Riley crossover splits your audio into three bands. Each band runs through its own oversampled processing chain with ADAA distortion and latency-aligned crossover phase. All three bands recombine through a 24-band master EQ, then a Class-A tube saturator, then a transformer coloring stage.

PER-BAND PROCESSING

Every band gets its own world.

Each of the three bands — Low, Mid, and High — has its own complete signal chain. Enable or disable any module per band. Solo or mute individual bands to dial in your sound.

MASTER SECTION

The final shaping pass.

After the three bands recombine, the signal runs through a 24-band master EQ, a Class-A tube saturation stage, and a transformer coloring stage. Everything you need to finish a mix — or master one — without leaving the plugin.

MASTER EQ

24 bands. Slopes to 96 dB/oct.

Twenty-four fully parametric bands with seven filter types each. Low Pass and High Pass filters can be cascaded up to 96 dB/octave for surgical cutoffs — that's sixteen biquads stacked per filter. Per-band pre/post-distortion routing lets you shape the signal before or after saturation. Solo any band to isolate its contribution to the mix.

USE CASES

One plugin. Every source.

Drums & Percussion

Parallel compress the lows for weight. Hard clip the mids for snap. Leave the highs clean for air. Solo each band to dial it in.

Bass & Synths

Saturate the sub for harmonic presence on small speakers. Spread the highs for width. Use mid/side to keep the low end mono while widening the top.

Vocals & Dialogue

Gentle saturation on the mids for warmth and presence. Compress the high band to tame sibilance. Spread the sides for a wider vocal image.

DISTORTION

Eleven shapes. Three units. Zero aliasing.

Each band has three independent distortion units, each with 11 waveshaper algorithms — from transparent Soft Clip and warm Saturation to aggressive Hard Clip, experimental Lazer Tech, and the unhinged Thrasher. Every shape runs through first-order antiderivative anti-aliasing (ADAA) with a built-in DC blocker, so you get the grit without the fizz. Drive pushes the signal in, Output trims it back, Mix blends wet and dry, and Amount scales the whole distortion section against the band's signal.

COMPRESSION

A serious compressor on every band.

Full VCA-style compressor per band with threshold, ratio, attack, release, and makeup gain — plus a soft knee (0-6 dB) and program-dependent adaptive release that loosens up on transients automatically. Switch between snappy linear-domain detection for punchy sources or smooth log-domain detection for transparent mastering. Real-time gain reduction metering per channel. Amount and Mix blend everything from gentle glue to full squeeze.

STEREO WIDENER

Width that holds up in mono.

Per-band stereo widener using micro-pitch overlap-add (OLA) detuning combined with a six-stage allpass decorrelation network. Asymmetric detuning (-7 cents left, +9 cents right) creates natural width without the phase smear of a chorus, while the allpass cascade decorrelates the signal across six break frequencies per channel for a dimensional, three-dimensional field. Zero latency, excellent mono compatibility. Add width to your highs without muddying the lows.

ANALOG BUS

Class-A tube & iron-core transformer.

A two-stage analog modeling chain sits on the master bus, after the EQ. First, an asymmetric Class-A tube saturator adds even harmonics and warmth with a built-in DC blocker to keep the low end tight. Then an iron-core transformer emulation adds gentle high-frequency rolloff and low-frequency saturation residue — the same character that makes classic analog consoles feel glued.

Three controls drive the whole chain: Drive pushes signal into the tube stage, Color sweeps the transformer's frequency response from clean to vintage, and Amount blends the entire analog path against dry. Dial in a hint of console glue or push it all the way into tape-like saturation.

OVERSAMPLING

Aliasing, handled.

Saturation and clipping generate harmonics above the Nyquist frequency. Without oversampling, those harmonics fold back into the audible range as aliasing — that fizzy, digital harshness on top of your saturation. FAT-X3 runs each band through a polyphase IIR half-band filter at 2×, 4×, or 8× the sample rate, pushes the harmonics out of the way, and then downsamples them cleanly.

The oversampling is applied per band, with automatic latency compensation between bands to keep the crossover phase-aligned. In addition, every per-band distortion shape uses first-order antiderivative anti-aliasing (ADAA) on top of oversampling — a second line of defense against aliasing at the waveshaper itself.
