With the advent of digital recording and editing, evaluating recorded evidence has become much more complex. Digital recordings can be manipulated more easily than traditional analog recordings, making them much harder to evaluate for alterations. This increases the chances of altered tapes being verified as authentic, or that alterations escape notice even by experienced examiners. Digital recording and editing can make it incredibly difficult to determine if recordings have been altered, because once they are digitized, anomalies can disappear or be mistaken for typical digital recording markers.
