LedFx processes audio input in real time and pushes light effects to networked LED devices over Wi-Fi

LedFx is a software system that takes an audio input source (system audio, microphone, or network stream), analyses it in real time, and drives addressable LED strips connected to networked microcontrollers (ESP8266, ESP32, Raspberry Pi running WLED firmware). The processing chain is: audio in → effect computation → network packet → device firmware → LED output. Communication is over Wi-Fi using network-level protocols, meaning LedFx can control multiple devices across a whole house simultaneously without a direct hardware connection. The browser-based UI on port 8888 provides real-time configuration and visualisation without requiring additional software installation.

Examples

LedFx on a Windows PC listening to Spotify; WLED firmware on ESP8266 controlling WS2812B LED strip; effects sync’d across multiple rooms.

Assessment
