What is LedFx?

Music to Light!

LedFx instantaneously transforms audio input into a realtime light show. No need to spend hours on syncing your LEDs to music - LedFx will do this all for you!

LedFx is a real-time music visualization program that streams audio reactive effects to networked LED strips. LedFx can control multiple devices and works great with cheap ESP8266/ESP32 nodes, allowing for cost effective synchronized effects across your entire house!


We are actively adding and perfecting the effects. Here are some of our favourites!

  1. Build your networked LED Strip.
    • For most, this is the difficult step. Don’t worry! There’s guides here and online, and plenty of people able to help on WLED and LedFx Discord.

    • Follow the WLED guide to connect the LED strip and ESP together:

    • Flash WLED to the ESP device:

    • Ensure all WLED devices are powered on, and connected to your Wi-Fi.

    • Test you can access the WLED web interface from your PC. If so, then you’re good to go!

  2. Install LedFx.
  3. Direct computer audio output to LedFx.
  4. Start LedFx.
    • Your WLED devices should appear in LedFx, automagically configured and ready to go! 🎆🔥

    • If not, on the left hand side, click on Device Management -> Find WLED devices button, or Add Device to add them manually.

    • If they’re still not showing up, make sure they’re powered on and properly connected to your WiFi.

  5. Start using effects!
    • Click on the device, select an effect eg scroll(Reactive), and press Set effect button.

    • Your lights should now be reacting realtime to your music! Enjoy the show 🌈
