Abstract: The identification and comparison of recorded gunshot sounds is a common signal analysis examination in the forensic audio field. When comparing two or more gunshot events in an effort to opine on their consistency, both qualitative evaluations and quantitative measures of the onsets of the compared shots are typically used. Prior research has established that high correlations can be found between recordings of multiple gunshots fired by the same weapon, given that the relative distance and angle of the weapon to the location of the microphone remain consistent. When computing cross-correlation values, a segment of time from one event is mathematically compared with an equivalent segment of time from a second event. The lengths of the compared segments for a given pair of gunshots may produce widely-differing results, based upon the differing conditions under which the gunshots occurred and were recorded.
