# Katana Meter

Katana Meter is a deterministic audio analysis engine designed for
LUFS, True Peak (sample-based approximation), gain calculation,
and ΔE (entropy-change) metrics.

It is intended for research, educational use, and technical evaluation.
The core is dependency-free and focuses on reproducible, transparent results.
