## What is GSDSP MagicFusion?

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).

### 5/5 — Best vocoder for iPad, bar none

*2026-06-27*

I was searching for a vocoder app that allowed for modulator and carrier to be freely assigned from different audio inputs, which was a surprisingly difficult task. Thankfully, I found MagicFusion! 

The app is incredibly deep, and the modulation options and implementation are beyond anything else I’ve seem on iPad. And on top of that, it sounds SO GOOD. Well worth the premium app price. If you want a full featured vocoder that rivals anything you’ve heard, even in a desktop environment, and also offers amazing versatility, this is what you are searching for.
