Convention Paper

Wideband Audio Recordings of Gunshots: Waveforms and Repeatability

Authors: Maher, Rob; Routh, Tushar

AES Convention 141 · Paper 9634 · September 2016

Abstract

For the purposes of audio forensics research we have obtained multichannel acoustical recordings of gunshots under controlled conditions for several firearms. The recordings are made using an elevated platform and an elevated spatial array of microphones to provide quasi-anechoic directional recordings of the muzzle blast. The consistency and repeatability of gunshot sounds is relevant to many areas of forensic analysis. This paper includes a description of the recording process and a summary comparison of the acoustical waveforms obtained from ten successive shots by the same firearm by an experienced marksman. Practical examples and applications are presented.
