SoundGram
A 2018 technology for embedding durable metatags and markers into an audio stream — steganography with cryptographic resilience.
SoundGram (2019) explores how information can travel inside sound without announcing itself. The system embeds metatags and markers directly into the audio stream — steganographic payload designed to survive ordinary listening, distribution, and imperfect capture.
The goal is not decorative watermarking. SoundGram treats the carrier as a channel: identity, provenance, and control signals woven into the waveform with an emphasis on cryptographic resilience. Markers remain recoverable when the stream is replayed, re-encoded within practical bounds, or passed through real-world environments where plain metadata would be stripped.
