A SoundCard is not a receipt. It is a living document of a vocal's identity — carrying the 512D profile, the full processing chain, before and after audio samples, loudness data, and artist DNA match — in a single shareable .ASC file.
Every decision made in processing that vocal is legible from the SoundCard — without requiring access to the original session, the original software, or the original engineer. The format is designed for portability without information loss.
A SoundCard is a vocal's passport. It carries identity. It grants access. It tells the story of how a voice was transformed.
Placing one SoundCard onto another triggers application of the source card's processing chain to the target vocal, adapted through the Chain Mutation layer. This is the foundation of the SoundCard marketplace — a vocal economy built on transferable intelligence.
