AudioReactive is a versatile Blueprint and Master Material combo for Unreal Engine.
This tool will let you effortlessly synchronize your project's visuals with music, using multiple audio stems directly from your tracks to drive dynamic visual effects, all without the complexity of frequency filtering.
AudioReactive Materials, Meshes, and Lights are now a click away! Anything you make reactive will have its own granular controls over all possible reactive parameters.
FEATURES
Real-Time Audio Interaction: Automatically sync any static mesh, material, or light with music or sound effects. AudioReactive translates audio signals into dynamic visual changes.
Unlimited Audio Tracks: Built-in dynamic support for unlimited input stems, allowing simple but scalable audio source separation and more precise control over which elements react to a chosen track.
Easy Blueprint Integration: Simple to set up and customize—no extensive coding experience needed. Add your own triggers, event-based animations, and sequencer functions.
Ultra Dynamic Sky Compatibility: Seamlessly synchronize day/night cycles and weather transitions to your track, enhancing immersion and atmosphere.
Motion Design Plugin Ready: Give your motion graphics an added boost from the AudioReactive Master Material.
Flexible & Scalable: Ideal for cinematic cutscenes, interactive media installations, live events, or full-scale game environments.
Performance-Focused: Designed to handle complex scenes while maintaining stable performance, even in demanding real-time applications.
Elevate your Unreal Engine projects with interactive, music-driven visuals—all powered by AudioReactive!

AudioReactive Blueprint Guide - v1.1 update in progress
If you have any questions or issues, come join me on Discord! I plan to keep developing AudioReactive and hopefully increase the development team from 1 to 2!
New Features In Version 1.1
Mesh Tagging system - a visual text ID tag in editor, identical to the assigned array index, that sticks with its corresponding reactive static mesh or light to easily track your reactive objects and lights with ease.
Reactive light enhancement to allow more light parameters to respond to audio.
Further UltraDynamicSky integration - Audio Triggered Lighting Flashes are here! Set your track number, adjust the loudness trigger threshold, set a custom delay, and even pick your own starting/ending lighting bolt location for full lightning bolt control.
Meshes and Lights are automatically set to 'moveable' when added to one of the reactive arrays.
Features in Progress
Widget Interface for easier control over scenes with large amounts of audio reactive meshes and/or lights.
Niagara Implementation - Allowing you to add your niagara object into a slot on the BP to give it built in audio reactive functionality, including scratchpad spectrum analysis and frequency response range variables.
Per track automatic audio float normalization for more predictable values when driving audio reactive effects.
