← Proof Not Tyler

Acoustic Two-Event Split

If Tyler Robinson alone fired a .30-06 from ~120 meters east, professional audio at UVU should tell one coherent supersonic-rifle story. Compiled Canon XA55 analysis in CK_FILE argues instead for two separated acoustic events — a distant muzzle blast and a louder stage/tent event ~46 m from the camera. That split is a central Proof Not Tyler argument: the fatal mechanism may not be the rooftop rifle shot.

Canon XA55 setup

On September 10, 2025, a Canon XA55 broadcast camera reportedly recorded uncompressed four-channel audio at 48,000 samples/second, positioned roughly 46 meters from the tent where Charlie Kirk sat. Phone footage merges events; professional channels preserve timing.

Three timing peaks (citizen analysis)

Offset	Event	Interpreted source
+114 ms	Early high-frequency energy	Supersonic precursor / Mach cone
+202 ms	Muzzle blast	Rifle fire ~120 m from camera
+321 ms	Loudest low-frequency peak	Stage/tent ~46 m — Charlie's position

CK_FILE summary:

"A rifle 120 meters away. A detonation at the tent. Two locations."

Why this challenges lone rooftop Tyler

A single Tyler shot should not, in this framing, produce:

1. A clear distant rifle signature at +202 ms, and
2. A stronger low-frequency tent/stage event at +321 ms

Analysts argue the +321 ms peak is not mere echo but the primary kill mechanism — device, mic charge, or close weapon — while the rooftop shot is misdirection, unrelated fire, or staged audio.

Proximity sound claims

Separate ProjectConstitu threads cite sound-signature analysis placing a shooter within ~36 feet of one recorder — incompatible with 120 m rooftop Tyler if that analysis holds.

Witness alignment

Limits

Audio analysis depends on source file authenticity, microphone placement, and analyst methods. No court has adopted the two-event model. It remains a hypothesis strengthened by professional multichannel recording claims.

Citizen Investigator Claims on X

(Challenges to the lone-rooftop /.30-06 attribution — Robinson is charged and presumed innocent until proven guilty.)

• July 2026 preliminary-hearing coverage on X was split: some accounts called the state’s DNA/video package “ironclad”; others (and defense reporting) stressed ATF inconclusive ballistics, DNA-method challenges, and “little mysteries” on scene gaps.
• Long-running citizen threads still highlight acoustic two-event claims, backpack/rifle concealment doubts, stairs-guy clothing mismatch, Miranda vs Discord timing, and GSR/physical-test gaps — see sibling pages under Proof Not Tyler.
• Page focus: Acoustic Two-Event Split. Competing official and citizen narratives both deserve documentation; neither substitutes for a completed trial record.
