Summary  
This report details an FBI forensic audio analysis conducted on specimens related to the RFK assassination investigation. Specimens Q1, Q2, and Q3 were examined for gunshot detection. Specimen Q1 is described as an analog copy with copying artifacts, limiting its analytical value. The original recording material could not be evaluated due to unavailable source data. Specimen Q2 and the source material for Q3 are identified as enhanced or 2nd-generation copies of the original recording. The analysis method "Frequency Selective Integrated Loudness Envelope Evaluation" is noted as unpublished in peer-reviewed journals. The examination concluded that the designated area on Q1 lacked sufficient quality to confirm gunshot classification, quantity, or weapon identification. Specimens Q1, Q2, Q3, and damaged tape segments were forwarded to the requesting office via FedEx on April 12, 2013. NE1 and NE2 items are retained.
