Autodafe Unveils Free Formant Filter Plugin for Sound Design

Autodafe has launched the Autodafe Formant Filter, a new free formant filter plugin tailored for vocal-style filtering, sound design, and synth processing. This plugin stands out thanks to its smooth, continuous morphing between the vowels A, E, I, O, and U, employing classic formant filter techniques.
Intuitive Interface for Real-Time Control
Designed with a focused interface, the Autodafe Formant Filter allows for real-time control, making it suitable for musicians and producers aiming for musical results. The plugin’s main features include:
- Continuous vowel morphing
- Intensity control for formant strength
- Dry/Wet mix
- Lightweight DSP and modern interface
This plugin is available in multiple formats, ensuring compatibility across various platforms. It supports VST3 (for Windows, Mac Silicon/Intel, and Linux), Audio Unit (Mac Silicon/Intel), Standalone (Mac Silicon/Intel, Windows, Linux), VST2 (Windows), and LV2 (Linux).
Freeware with Optional Supporter Edition
The Autodafe Formant Filter is released as freeware, making it accessible to all users. Additionally, there is an optional Supporter Edition available for €5 for those who wish to contribute to the plugin’s ongoing development. Both versions of the plugin are functionally identical, ensuring that users have access to all features regardless of the version they choose.
Cross-Platform Compatibility
Built using JUCE and C++, the plugin has been rigorously tested on various operating systems, including macOS (Apple Silicon and Intel), Windows, and Linux. This makes it a versatile tool for producers working across different environments.
