The first additive engine sound synthesizer for Unity. One recording in, fully procedural engine out. Reproduce any engine from your own recording or a YouTube clip.Tested on desktop (Windows, macOS). WebGL is not supported. It should work on all other platforms, but it hasn't been tested on Android or iOS.While every other engine sound asset on Unity stitches together recorded samples, Fubos Engine Sound takes a different path. It's the first engine sound synthesizer for Unity built on additive resynthesis - a technique that has never been used in games. Sound is generated in real time, with no samples and no crossfades.How it worksFeed the tool a single recording of an engine accelerating - your own or a recording from YouTube. The analyzer extracts the recording's harmonic structure and packs it into a compact .eng file. The synthesizer plays that profile back in real time, reshaping the sound to match the current RPM and load. Every cycle is unique, and transitions between RPMs stay smooth.Key featuresRealistic sound extracted from a real recordingSmooth RPM transitions, no audible seams or loopsSound varies naturally from cycle to cycle — no static "buzz-saw" feelCompact .eng format, easy to build a library of enginesHigh-performance DSP - Burst-compiled, vectorized math, zero runtime allocationsSupport for 2-stroke and 4-stroke enginesFull control through Unity's AudioSourceIntegrate in just a couple of lines of code - built for the simplest possible workflowComplete documentation covering every parameter with usage examplesWhat's in the boxEngineForge Analyzer editor tool for extracting an engine profile from a WAV9 ready-to-use engine presets - Italian V6, Italian V12, Japan I4, Japan I6, V8 and moreSynthesizer for real-time playback of the profileDemo scene with a simple car and demo profilesPDF documentationSupportQuestions, feedback, or want to share what you've built?
