SpecCraft by Three-Body Technology

Cut Narrow, Boost Wide, and On the Fly.

Introducing SpecCraft, a next-generation dynamic resonance suppressor, spectrum compressor, and smart EQ. It specializes in eliminating the greatest enemy in your mix: unwanted resonances. Whether it’s harsh shrills or muddy booms, SpecCraft identifies them all and dynamically applies matching suppression at each and every audio frame.

But wait, there’s more! SpecCraft not only helps you 'seek and destroy' resonance problems but can also fill the void left behind by generating real-time spectrum compensation curves, ensuring no dynamics loss or artifacts due to resonance suppression.

With SpecCraft, your mix stays clean, balanced, and full of life from start to finish.

Perfected Resonance Suppression, Practical Workflow

Resonances aren’t inherently bad—unwanted resonances are. That’s why they’re better adjusted with care than subdued with force. SpecCraft’s complete and concise controls allow you to locate unwanted resonances faster than ever, while its meticulously crafted algorithms suppress them with unmatched efficacy. And all of this is done with just simple clicks and drags, in the ways you’re most familiar with when using dynamics processors.

Real-Time Adaptive Threshold Control

In the meantime, SpecCraft offers a smart amplitude-based real-time thresholding algorithm, which continuously finds the optimal amplitude threshold for the resonances that need suppression, functioning like a self-adaptive threshold automation. You can choose to make threshold adjustments fully automated, fully manual, or anywhere in between. You’re Sherlock, and SpecCraft is your Watson.

Self-adaptive Spectral Compensation

As in the yin-yang equilibrium, if we only suppress and do not enhance, the overall audio spectrum inevitably becomes flat and lacking. To redress the balance, you must have heard of a common mixing practice: applying narrow Q cuts to remove harsh resonances, followed by broad Q boosts to enhance the overall frequency band. Building on this approach, SpecCraft incorporates its proprietary 'self-adaptive spectral compensation' algorithm, which continuously calculates three potential global spectrum compensation curves based on the amount, frequencies, and levels of the suppressed resonances. These smart enhancements enable SpecCraft to avoid flat, unnatural, and overly compressed sound while effectively managing resonances.

Spectrum Slope

Different audio content can exhibit varying frequency balances, making a flat threshold curve difficult to manage in all situations. With Spectrum Slope, you can tilt the spectrum display from 0 dB/OCT to 12 dB/OCT, ensuring that both high and low unwanted resonances interact equally with the threshold curve.

Priority Curve

Like all Three-Body Technology products, SpecCraft offers maximum flexibility. In addition to the Threshold, Adaptive Threshold, and Slope controls, the meticulously designed Priority Curve lets you further fine-tune the amount of processing across different frequency bands to sculpt the frequency envelope with surgical precision.

Profiling

With SpecCraft, you can apply a custom frequency response curve as your threshold—similar to EQ-matching, but executed dynamically on every audio frame. You can choose from the preset threshold profiles, extract from audio files, or even record and capture one on the fly.

Zero Delay Feedback Level Detector

ZDF (Zero Delay Feedback Filter) is a digital filter structure that offers better sound quality than other structures under rapid filter coefficient changes. As a result, it is often used in software synthesizers. Now, Three-Body Technology has innovatively applied ZDF to SpecCraft's envelope detector, enabling it to deliver superior sound quality compared to conventional envelope detectors, whether processing fast percussive sounds or continuously changing sibilants.

Analog-modeled Resonance Suppression/Compensation

As a digital frequency-domain processor, SpecCraft steps beyond mere digits. At its core, it functions like thousands of analog-modeled units orchestrated with digital precision. Whether suppressing or compensating at any frequency, SpecCraft models its behavior after renowned classic hardware, delivering a natural, warm tone rather than the coldness typical of digital dynamics processors.
