GSDSP MagicFusion

This advanced audio effect plugin offers precise spectral fusion and multi-curve vocoding. It allows users to extract spectral characteristics from one audio source and apply them to another, enabling detailed transformations from subtle shading to extreme effects.

Highlights
  • Multi-curve spectral vocoding
  • Frequency-domain processing
  • Independent fusion amounts per frequency
  • Dynamic response control
  • Formant shifting
  • AUv3 audio effect plugin

The world’s first frequency-domain vocoder with multi-curve control and precision spectral fusion. Multi-Curve Spectral Vocoding MagicFusion is a multi-curve spectral vocoder workstation operating entirely in the frequency domain. Instead of relying on bandpass filters and envelope followers, it extracts the spectral characteristics of a modulator and applies them to a carrier, enabling precise, customizable vocoding across the entire spectrum. Apply independent fusion amounts per frequency or frequency range, then mix, modulate, and spread them to create anything from subtle vocal shading to extreme spectral transformations. Vocoder Signal Flow MagicFusion requires two audio inputs: the carrier (main input) and the modulator (sidechain). The plugin extracts the modulator’s spectral envelope and applies it to the carrier, creating a fused signal where both sources interact. This process provides clean, flexible control over the degree of spectral fusion and allows highly detailed shaping across the frequency spectrum. Dynamic Response & Formants Adjust the Smooth control to define how quickly the vocoder reacts, from fast, precise transitions to slower, more rounded movement. The Formant parameter shifts the spectral character of the modulator, while Detail adjusts the complexity of the filter response — from clean, intricate results to more organic, pumping behavior. MagicFusion is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX).

Technobabble: Synchronous polyphasic temporal compression for the coherent transsubstantiation of the phase-modulated frequency spectrum into a cross-dimensional, entropy-resistant acoustic singularity... to put it in simple terms: a baryonic resonance oscillation with fractal phase inversion that deconstructs the continuous time vector within the Hilbert space, freezing it inside an infinite, dimensionless audio event horizon. JAX Kryostatic is an AudioUnit (AUv3). AudioUnits require an audio host application. We produce audio tools exclusively for Apple platforms. The audio effect processor freezes your audio stream in real time. At the heart of its visualization lies an energy correlometer, alongside a dual stereo FFT waterfall display with adjustable flow speed. Using a "Touch and Slide" interface, you can intuitively freeze and shift the live stream's spectrum, visibly - even into extreme ranges. The freezing effect itself is automatic or freely adjustable, ranging from "Soft Iced" to "Hard Iced." So JAX Kryostatic serves equally well as a creative tool for sound design or simply as a musical analysis utility. This AudioUnit is highly optimized for real-time audio processing and very low CPU usage, as its entire graphical visualization is de-coupled and calculated / rendered directly on the GPU. Our new concept involves releasing some of our fully produced songs alongside our FRONTIER SERIES Audio Units. In doing so, we aim to illustrate our new guiding principle: providing musical tools rather than chasing obscure trends of noise production.
