Audio Forensic Analysis Procedures for User Generated Audio Recordings

The widespread use of handheld smartphones and other devices capable of recording audio and video means that user generated recordings (UGRs) are increasingly presented as evidence in criminal investigations. Combined with other recordings from law enforcement systems, home surveillance systems, etc., the availability of UGRs may offer important audio forensic insights. Forensic handling of UGRs requires best practices for assessing authenticity and integrity of the recorded information. The presenter will discuss their research on scientific and reliable comparison and synchronization of audio recordings of the same incident captured concurrently by multiple unsynchronized recording devices at the scene.

This webinar was hosted by the NIJ Forensic Technology Center of Excellence on November 29, 2022.
