Audio Enclosure Manifests and Content-Addressed Media Storage
Broadcasting high-fidelity audio streams requires rigorous tracking of codecs, sample rates, duration, and cryptographic content hashes. Chantey structures podcast episodes and audio dossiers as durable catalog files with content-addressed storage references.
Enclosure Invariants
- Content-Addressed Audio Integrity: Audio files verify against immutable SHA-256 CAS hashes (
urn:cas:sha256:...) to guarantee bit-exact permanence. - Standardized Codec Declarations: Frontmatter metadata explicitly specifies codecs (FLAC, OPUS, AAC), sample rates, and channel configurations.
- Decentralized Enclosure Mapping: RSS enclosures and streaming clients resolve media assets locally without relying on fragile third-party CDN links.
Content-addressed audio storage protects podcast archives from bit rot and broken enclosure links.
