Phase VI — Project Helix

Hear the event.
Understand the physics.

Spatial acoustic intelligence built from measurable evidence. Calibrated instruments. Cryptographic provenance. Physics-first correlation.

The Resonance Platform

Eight integrated products covering the full lifecycle from acoustic acquisition to evidentiary output.

Detect

Real-time acoustic classification with ML-powered detection and direction of arrival.

Mesh

Cross-node spatial correlation turning individual observations into located incidents.

Field

Deployment planning, site survey, and mesh optimization tools.

Fleet

Large-scale node management, OTA updates, health monitoring, and predictive maintenance.

Evidence

Cryptographic provenance chain producing court-admissible evidentiary packages.

Lab

Research environment for algorithm development, model training, and acoustic analysis.

Edge

On-node runtime handling acquisition, DSP, privacy filtering, and local inference.

SDK

Public developer library for building custom acoustic detectors and integrations.

12-Stage Processing Pipeline

From acoustic wavefront to evidentiary output in milliseconds. Every stage produces measurable, attributable data.

1 Acquisition

12-ch array capture at 48–192 kHz, hardware-timestamped, PPS-locked

2 Calibration

Per-channel gain, phase, and frequency response correction

3 Detection

Adaptive energy thresholding with noise floor tracking

4 Feature Extraction

MFCC, spectral centroid, ZCR, envelope, WavePrint fingerprint

5 Classification

ML inference on NPU — multi-class with confidence and alternatives

6 DOA Estimation

VectorWave beamforming — azimuth, elevation, confidence cone

7 Atmosphere

Wind, temperature, humidity correction for propagation speed

8 Privacy Kernel

Real-time speech detection and suppression before any storage

9 Signing

Ed25519 cryptographic attribution of every observation

10 Correlation

Cross-node temporal and spatial fusion via TDOA + APS

11 Incident Fusion

Multi-observation evidence aggregation into located incidents

12 Provenance

Tamper-evident chain producing court-admissible evidence packages
