Abstract
In certain cases, there may be a question about the authenticity of an audio forensic recording. Like any physical evidence, audio forensic recordings are subject to potential questions about authenticity: is the recording complete, unaltered, and consistent with the stated circumstances of its creation? For example, an individual may claim that a recorded conversation has been edited so that certain critical utterances are inserted or edited out. Other cases may involve suspicion that the asserted time, place, and circumstances are not what was claimed (Audio Engineering Society 2000). What is authenticity? Can it be guaranteed?
