About LedFx

LedFx is software that turns audio input into real-time lighting effects for network-connected LED strips and matrices. It works with controllers such as ESP8266, ESP32, and Raspberry Pi 4, commonly running WLED firmware, and can handle multiple devices together for synchronized effects across rooms.

You install LedFx on a Windows, macOS, or Linux computer and control it through a browser interface at http://127.0.0.1:8888. After connecting WLED devices to Wi-Fi, you can scan for them in LedFx or add them manually, then select an effect for each device. The site provides installation guides, command-line options, device firmware notes, and setup instructions for routing system audio.

It suits people who already have or plan to build addressable LED setups and want music-reactive lighting without programming each song. Basic wiring, firmware flashing, and network setup are required.
