SpecCraft is a smart resonance suppressor, spectrum compressor, and EQ that dynamically removes unwanted resonances while compensating the spectrum and dynamics for a clean, natural mix.
Core Resonance Suppression
SpecCraft identifies harsh or muddy resonances in real time and applies precise suppression tailored to each audio frame. Its intuitive controls let you locate problem frequencies quickly, while the processing uses analog-modeled algorithms to maintain a natural, warm character rather than a cold digital feel.
Adaptive thresholding continuously finds the optimal amplitude threshold for suppression, with full manual or automated control. A spectrum slope tilts the threshold to handle high and low frequencies evenly, and a priority curve fine-tunes processing across bands for surgical envelope shaping.
Spectral and Dynamics Compensation
To avoid a flat or lifeless mix after suppression, SpecCraft generates compensation curves based on the suppressed resonances. Self-adaptive spectral compensation offers three global EQ curves to restore tonal balance, while dynamics compensation restores loudness envelope for perceived energy.
Formant boost preserves spectral character, and treble compensation can maintain cymbal presence or act as a de-esser. These tools work together to ensure the mix stays balanced and full, without unnatural artifacts or loss of clarity.
Flexible Processing and Sound Quality
A zero-delay feedback filter in the envelope detector improves sound quality on fast transients and sibilants. Zero latency mode uses minimum phase filters for real-time use, while lookahead preserves transients during attack. Oversampling options reduce aliasing for pristine results.
Side chain controls support Left/Right or Mid/Side processing with adjustable stereo linking, from full stereo to dual mono. Profiling lets you use a custom frequency response as the threshold, extractable from audio files or captured live. The interface includes a real-time frequency display and side chain monitoring.
Workflow and Applications
SpecCraft is designed for mixing sessions where unwanted resonances from vocals, drums, or cymbals need fast attenuation without dulling the mix. Its dynamic, frame-by-frame operation adapts to changing material, making it effective on complex program audio.
For live performance or arranging, zero latency mode ensures real-time responsiveness. The external side chain and profiling add flexibility for creative or corrective tasks. Presets, undo/redo, and A/B switching streamline workflow, while user-defined defaults and theme options personalize the experience.
