Audio Steganography, Faster and Friendlier: My Dive into Spectrogram

A few days ago, I stumbled across an interesting blog post by Solusipse about hiding images in sound—more specifically, encoding them into the spectrogram of an audio file. It reminded me of old-school tech like dial-up modems and the ZX Spectrum, but with a modern twist. Naturally, I had to try it. Getting Started... and Stuck Solusipse provides a Python script, spectrology.py, that takes an image and converts it into an audio waveform whose spectrogram visually resembles the image. I cloned the repo, followed the README, and ran the script, hoping for a cool output. But things weren’t so smooth. The script hit an error out of the gate. Can't blame them, the code was over 10 years old
