Sound Steganography
Audio is a rich medium for hidden data. Human hearing covers 20Hz-20kHz, but digital audio can carry frequencies beyond that range. And even within the audible range, subtle modifications are imperceptible.
Silence
Pause durations encode binary data. 0.1s = 0, 0.2s = 1. The silence between words carries “WOLNO.”
Spectrogram
Sound that looks like noise — but when visualized as a spectrogram, it spells “WOLNO.” Interactive demo included.
AETHER-2L
The full protocol: a two-layer audio composition. Humans hear music. Machines decode the hidden channel.
The music plays. The message hides. Both are real. -”
