Audio recordings of gunfire are often of evidentiary interest in legal proceedings, requiring the opinion of experts with combined knowledge of audio engineering, acoustics, and signal processing. The recordings originate from diverse instruments such as body-worn cameras, security camera systems or telephones, and can be complicated by multiple factors that affect signal analysis. This paper provides an overview of types of forensic audio gunshot analysis and an evaluation of the reliability and limitations of particular techniques that have been used by experts in the field of forensic audio.
