Cryptochords Framework: Multi-Layered Symbolic Audio Steganography for Covert Communications

Conventional audio steganography methods that operate in the physical domain (LSB modification, phase encoding, or echo hiding) are fragile under lossy compression (MP3, AAC, Ogg Vorbis) and acoustic air-gap re-recording. This paper presents the formal specification of Cryptochor...
