Chapter 6 of 10 · Steganography 60%

🎵 In 1999 Aphex Twin hid his own face inside a track. It only appears when you open the song in a spectrogram. Could you spot a picture drawn in sound?

Audio hides secrets your ears skip. A spectrogram turns sound into a picture, and hidden text, faces, and Morse tones jump out. You'll use Audacity and Sonic Visualiser to read messages drawn in the high frequencies. No GPU needed. 🔊
