Framework
The baseline layer included with every HFA dataset—rights-cleared recordings and consistent technical structure designed for modern model training and evaluation.
Foundations defines the baseline deliverable for every dataset: clean recordings, consistent structure, and core descriptive metadata. It is intentionally designed to be useful across research, prototyping, and enterprise evaluation.
Foundations emphasizes consistency and repeatability. The exact contents vary by dataset, but the technical baseline stays stable across the catalog.
Controlled recording environments, consistent gain staging, and clean source handling.
Predictable file formats, naming patterns, and structure for programmatic ingestion.
Dataset-level documentation plus baseline descriptive fields for filtering and organization.
Consistent foldering and clip layout so teams can scale usage across multiple datasets.
Foundations provides the base audio and structure. Proteus Standard™ adds integrity, provenance, and audit-ready documentation. Orpheus is an optional suite that extends capability for advanced workflows.
Most teams begin with Foundations + Proteus, then add Orpheus layers only if their workflows require advanced annotation.
