Audio Steganography (WAV LSB)

Hides an encrypted message in the least significant bits of PCM samples. The source audio can be uploaded as MP3/OGG/WAV, but the resulting container is saved only as WAV.

🔐 Crypto core: Argon2id + AES-CTR + HMAC-SHA256 | dual-block container with fixed quanta | Encrypt-then-MAC
After embedding, the container cannot be converted to MP3/OGG/AAC — compression destroys LSB data. Use the original WAV container for extraction.
