Abstract
Digital audio recording has become more prevalent than its analog predecessor. When a digital audio recording is presented as forensic evidence in legal proceedings, the party introducing it must show that it has not been altered since the time of its production. This kind of originality and integrity examination is a complex task in the field of forensic science and has become an important function of a forensic audio laboratory.
