The VST3 Host Server for Live Sound

Housed in a tour-tough 2U chassis, the Fourier Audio transform.engine is a VST3 plug-in host server that lets live sound engineers reliably run VST3 plug-ins with low latency and interface them seamlessly with all of their Dante-enabled equipment. Combining the power of two industry standard protocols — Dante and VST3 — transform.engine represents a revolution in signal processing for live audio, enabling access to a Dante-connected universe that has long been enjoyed in studio environments.

Leveraging a Dante-connected live environment

Designed by the engineers responsible for DiGiCo consoles, transform.engine can interface natively with these boards via Dante with the addition of a console upgrade card. The seamless interconnection of digital consoles with other Dante-enabled gear and the vast universe of VST plug-ins puts live sound engineers in the cockpit of a comprehensive live control center encompassing nearly all their equipment, complete with the advantages of time-based processor programming, instant settings recall, and error-free repeatability.

Sandboxing for rock-solid reliability

The live sound engineers at Sweetwater know that absolute reliability is critical when you’re in the front-of-house hot seat. That’s why Fourier Audio designed transform.engine with a unique architecture wherein individual signal chains are sandboxed. If one of your plug-ins were to crash, the system takes note of it and restarts that chain, with all of the other chains remaining unaffected. This all happens automatically and seamlessly, with the misbehaving plug-in being restarted before you even notice a problem. In addition to 64 bidirectional channels of redundant Dante I/O, transform.engine is spec’d with dual redundant, switched and filtered IEC power inlets for ultimate peace of mind.

Studio-grade processing power at FOH

The lowest-latency VST3 plug-in hosting solution on the market, Fourier Audio’s transform.engine facilitates creativity with access to studio-grade processing capabilities. Meticulously designed to handle the intricacies of live sound production, this robust platform provides seamless integration into live audio workflows and gives engineers direct control over their plug-ins and the ability to optimize their workflows efficiently. A turnkey solution, transform.engine is easily controlled via a remote Windows/maOS client app. This eliminates the need for complex setups, allowing engineers to simply connect to the engine from the client, install their plug-ins, and begin processing.
