Detecting Hidden Data: Audio Steganography vs. Steganalysis

Audio steganography is the practice of hiding a secret message inside a digital audio file without altering the perceived sound quality. Unlike cryptography, which encrypts data to make it unreadable, steganography hides the very existence of the message entirely. By exploiting the limitations of the Human Auditory System (HAS)—which cannot detect minute changes in sound frequency or amplitude—senders can mask texts, images, or even other audio tracks inside a standard song or recording.
