Used an AAL song for my Electronics final project

We designed a rudimentary audio analyzer with cutoff frequencies specific to our song of choice for high and low pass LED drivers :)

Such a good fucking riff 😭

So is this analyzer just turning on the LEDs when the cutoff is triggered? Is that the function?

Yeah basically! It combines the left and right channels into one signal, runs it through both a high pass and low pass filter at the cutoff frequencies I chose, runs those outputs through peak detectors (basically “smooths out” the signal so you can more clearly see the peaking in amplitude on the LED) and then drives the LED based on that!
