Hey all,
I’m sure this is all over the internet, but I wanted to hear the forum’s advice.
Anyone have any builds for a frequency spectrum analyzer and would it be something a relative beginner could build? I’ve been wanting one to slap somewhere into an audio chain to help with sound design and mixing.
I could save up to buy one or use a software solution, but I’d rather make one myself for the hell of it.
Not sure if these kind of beginner “How do I do?” threads are well received, so sorry in advance. <3

I would start with software (say on an android phone) and “build” an interface. Even if you built from scratch im not sure I’d trust my own calibration. Nice project idea.

Spectrum Analysis is a bit more complicated than say an oscilloscope. My guess is you would need a teensy or something at least to make the FFT calculations necessary.
-edit-
A quick google brought up this led matrix project. So yes, this is a thing you can do. The code is right there on their github link.

They get cool points for using jean michel jarre for the demo audio:
