- Auth: none declared

Classify infrasound source type from spectral features.

Discriminates between 4 source types using spectral centroid,
duration, trace velocity, peak pressure, and lightning
correlation.

Source types:
    eruption (0): broadband 0.01-5 Hz, sustained, moderate trace velocity
    bolide (1): impulsive 0.5-5 Hz, short, high trace velocity (>380 m/s)
    explosion (2): impulsive 1-20 Hz, short, strong pressure
    thunder (3): 1-100 Hz, repetitive, lightning-correlated

**Pricing:** Included in subscription tiers (legacy list price: GET /api/v1/billing/pricing).
