Using Spectrographic Analysis to Identify Acoustical Spaces for use in Audio Forensic Applications

Document Thumbnail

It has been found that the nature of spectrographic information provided by the human voice can yield evidence to identify a person whose voice has been previously recorded. Do spatial environments display similar spectrographic distinctions that can be used to identify the location in which a specific audio recording was captured? This paper will provide data gathered from various audio recordings of specific locations in order to obtain possible environmental identifications. The purpose of this research is to prove or disprove that acoustical spaces contain spectrographic characteristics that can be used to verify where an audio recording has been captured.
