I have been working on a number of FastLED based lighting projects over the last 7 years and many of them have involved audio responsivity. This has been using both the wonderfully simple to use MSGEQ7 and also my on FFT in code on the Teensy platform.

As I’m getting more involved with WLED, I wanted to migrate my existing projects from my own propetrory protocol over to one that would be compatible with WLED. I therefore created WLED-Sync to allow anyone to be able to both send and receive WLED compatible audio sync data in their own projects
