I did a side to side comparison of a Analog based Spectrum analyzer and a FFT based one.
Based on performance, can you replace your double MSGEQ7 setup with a ESP32 and FFT library?
I compared both versions with a line input and a Microphone input and combined all in a video.
To compare, I used the same code( Sketch) but both with it’s own plugin to get the frequency information. So, one uses a FFT libary and the other uses my existing hardware with two MSGEQ7 and Frequency board.
This is an open source project, all schematics, software and building instructions are available for you. Use it, change is, heck even sell it. It’s ok but if you do one or more of the above, please give me credit by linking back to my channel.
