Audio authenticity is rarely one “smoking gun”. Instead, multiple weak signals combine to build confidence.
Two useful MVP indicators
- Band-limit ratio: synthetic or recompressed audio often shows unnatural frequency roll-offs.
- Discontinuity score: abrupt spectral/energy changes can indicate splicing, edits, or stitching.
CanonProof treats AI opinions as advisory signals — they never decide the outcome alone. The outcome comes from explainable indicators and scoring.
