Here is a spectrogram of the track, "Look" from the album, "Songs about my Cats" by Venetian Snares.

Aphex twin did something similar, but this is more playful in my opinion.

This is very interesting what was the Aphex Twin’s track with this concept?

Its usually called 'formula' or 'equation' - B side of 'windowlicker'. There's a video at the link below

I once (badly) did something similar as a student [1].

Unfortunately it's in Matlab so I can not run it any more.

You know a personal license is only $149 USD right? You could then run your old code. Toolkits for home are $49.

$149 is still a significant amount for many people. Especially for something non-essential.

If you want to run it again you could try Octave, an open source Matlab alternative.

I also made something similar using Python a long time ago [1]. It's a extremely simple script so it should still work.

Warning - this music freaked my dog out!

From the look of the pictures there's a log() missing somewhere, no?

Mick Gordon did some fun hidden spectrogram imagery in the Doom 2016 soundtrack.

He talks about that and plenty of other cool stuff in his talk at the 2017 GDC conference. One of my favorite conference talks ever, he did so much cool experimentation to get the sounds he used on the soundtrack, and watching his talk is one of those moments where you really get to see a master of his craft let loose and explain his process.
