Debunked

Bad Analysis, Corrected

Viral audio forensic claims that don't hold up under scrutiny. Each entry details the original claim, the methodology errors, and the correct interpretation.

COMMON METHODOLOGY ERRORS

  • ✗ Confusing echoes/reflections with separate gunshots
  • ✗ Treating visual waveform features as evidence of editing
  • ✗ Ignoring codec compression artifacts in spectral analysis
  • ✗ Applying indoor acoustic models to outdoor environments
  • ✗ Cherry-picking frequency bands to support a narrative
  • ✗ Misidentifying AGC behavior as volume manipulation
  • ✗ Using frame-based video sync for TDOA multilateration
  • ✗ Hardcoding conclusions before running the analysis
ACOUSTIC TOOL CRITIQUE METHODOLOGY ERROR

"calcrack" — Forward Model Disguised as a Solver

Jordan Henshaw's calcrack tool (@jordanhenshawhq) is presented as acoustic source localization software but is architecturally a forward model, not an inverse solver. It requires the user to manually position a shooter and evaluates fit — it does not solve for the position from the data.

✗ Circular error metric that can't distinguish direction — only evaluates radial fit
✗ User-adjustable "bias" parameters allow tuning toward any desired result
✗ No uncertainty quantification — no confidence intervals, no Monte Carlo, no residual analysis
✗ Forward model architecture: user supplies the answer, tool evaluates it — this is not solving

A tool that lets the user dial in their preferred answer is not forensic analysis.

ACOUSTIC TRIANGULATION DEBUNKED

Bray's "Acoustic Fingerprint" TDOA Analysis

Claims to locate a shooter via 5-signature TDOA multilateration across 6 cameras. Cross-correlation reveals 125–321ms sync errors (43–110m spatial error) — 4–5x the camera baseline. Shooter position hardcoded before analysis runs.

✗ Synchronization errors of 125–321 milliseconds — equivalent to 43–110 meters of spatial error
✗ Shooter position hardcoded as a constant in the script before the analysis runs
✗ Cameras producing inconsistent results manually excluded without statistical justification

MULTI-DOMAIN ANALYSIS DEBUNKED

The "Epicenter Theory" — Shaped Charge, Decoy Shooter, Ballistic Gel

Claims a micro shaped charge in a microphone battery killed the victim, not a rifle. Fatal internal contradiction: "radial expansion" evidence is incompatible with directional shaped charge jets — the author himself acknowledges this. Flawed optical flow code, circular Strouhal calculation, synthetic "replication" scripts.

✗ Foundational optical flow code misuses physics terminology — detects wavefronts, not epicenters
✗ Published "replication" scripts generate synthetic data from hardcoded values
✗ Bray's own article states cell phone audio cannot reliably distinguish the sources he claims to identify

SCRIPT ANALYSIS METHODOLOGY ERROR

Synthetic Signals and Hardcoded Conclusions

Jon Bray's acoustic analysis scripts (followtheepicenter.com) are presented as forensic audio analysis but contain fundamental architectural issues that disconnect the outputs from the evidence recordings.

✗ Generates synthetic test signals rather than analyzing actual recorded audio
✗ Hardcodes shooter positions before "running" the analysis
✗ LLM-generated methodology with fundamental physics errors
✗ Outputs look like forensic results but are mathematically disconnected from evidence

When the conclusion is in the code before the data is processed, it's not analysis — it's illustration.
