The forensic audio analysis by Rob C. Maher of the 2024 Trump assassination attempt has been peer-reviewed and published in the Journal of the Audio Engineering Society. This is great news for visual and audio investigations! aes2.org/publications...

Diagram explaining how the timing between a bullet’s supersonic shock wave (“crack”) and the muzzle blast (“pop”) can be used to estimate the distance between a shooter and a microphone. Three scenarios (T₁, T₂, T₃) show a rifle firing a supersonic bullet past a microphone. In each scenario, the ballistic shock wave cone reaches the microphone before the slower muzzle blast sound. To the right of each diagram is a waveform: a sharp spike labeled the shock-wave “crack,” followed by a later cluster of peaks labeled the muzzle-blast “pop.” The time delay between these events (t_d1, t_d2, t_d3) increases as the microphone is positioned farther downrange. A formula shows distance = t_d / (1/c − 1/v), where c is the speed of sound and v is bullet speed. Text boxes explain: “Downrange timing between shock wave ‘crack’ and muzzle blast ‘pop’ gives distance estimate between shooter and microphone,” and “For investigation of Trump assassination attempt: microphone signal was from the lectern.”

A 50-year-old song by Leeuwarden (my hometown!) artist Sido Martens has suddenly racked up millions of Facebook views — but he only heard via Universal and doesn’t know which vid used it. He’s asked if the OSI/@quiztime.bsky.social community can help find out: www.youtube.com/watch?v=E-yT...

A newspaper article featuring a large photo of an older man with short white hair holding an acoustic guitar in a living room. The headline reads “Video met oud lied Martens viraal in VS,” and the article discusses musician Sido Martens and the unexpected viral use of his decades-old song.
