I built a project taking usb mic input and adjusting an led strip (NON-ADDRESSABLE) colour using the volume.
A pretty simple and uninspiring map of volume to a colour map (think "jet" from matlab or similar).
All well and good but not great.
When nearly complete I had found a github repo (I think) which applied FFT to an mp3 file and played the mp3 file while adjusting the (non addressable) led strip in time with the music.
I discounted it at the time because it didn't have mic input which was what I was looking to do at the time but now that I can do that I'd like to revisit the FFT software that I saw.
For the life of me I cant find it again.
All my searches are swamped with the github repo that controls addressable led strips. not the 5050 strips I thought I had seen code for.
Can anyone point me to the one I thought I found?
