Hi, I was wanting to try to make some custom headphones. The headphones themselves wouldn't really be anything special but what is on the sides is what i'm wanting. On the sides I was wanting LEDs in a circular fashion working as a spectrum analyzers to what ever music I play. A visual idea of what i'm wanting is the GIF below, the way the analyzer is working in the background is how id want it on the headphones except in the opposite direction where the bars go outward.I also would like to have it to where it had a switch where i could turn the analyzer off but still listen to music without it running. I don't care on how it works i just want it to not be too expensive and i want it to where it could look a little professional and clean

 

To break the audio spectrum into three frequency bands, search this forum and the innergoogle for "color organ". Lotsa circuits out there.

The animation depicted in your image, as shown, would require pretty high spatial resolution if maintained in the area of a typical headphone. It would probably take tens of thousands of LEDs. Could you get by with 100 pixels or less?

 

i didn't want it to be like that i was just saying to look and move similar to it. it would probably be less than a 100 leds

 

it really depends on how big everything has to be (like the PCB with all of the electronics), size and type of battery for it, and the size of the headphones.
