AB  - This paper describes some practical aspects for forensic analysis of tell-tale sounds in gunshot audio recordings. Gunshot recordings obtained from a microphone located sufficiently close to the scene of the shooting incident have the potential to reveal relatively quiet sounds associated with the firearms mechanical action: trigger, hammer, and cocking mechanism, the ejection of spent cartridges, and the positioning of new ammunition by the gun's automatic or manual loading system. In some cases, close recordings may provide clues about the type of firearm and ammunition used. However, audio recordings of gunshots typically contain the extremely loud report of the muzzle blast, background noise, and reverberation that may limit the ability to identify and classify tell-tale sounds. Examples are presented to show the features and some limitations of acoustic gunshot sound analysis from close recordings
