Desktop Audio Visualizer - Spectrum Analyzer - ESP32

281219 Like and subscribe. This is an archive, check the link in the end if you are owner. Powered by a dual core, 240MHz CPU with 4MB of RAM, it runs a Fast Fourier transform to generate audio data at 60 frames per second and drive a display that operates at up to 500Hz - far faster than my camera and with much more dynamic range. It looks amazing in person!

I'm trying to decide whether to Kickstarter it or release it as a project here (or both). Would you pay for assembled one or prefer a kit with PCB? Or just schematics, etc? Let me know in the comments.

Please share the video if you like the project!
