In Audio Forensics, it often comes down to ears versus microphones. In one corner, we have the human ear with all its amazing capabilities. In the other corner, the fantastic piece of technology known as the microphone, with its ability to record sound to a digital file or tape for later playback.
A confrontation between an inmate and a Corrections Officer leads to accusations of mistreatment on one side and claims of justifiable action on the other. It was one person's word against another until an unexpected recording came to light and, with the help of sophisticated audio forensic analysis and processing, the truth was revealed.
Pocket dialing occurs when a mobile phone's touch pad is pressed by something in a person's pocket or purse, or, if the person happens to sit down a certain way, a part of their anatomy. If the pressed key or screen surface area is programmed to dial or redial a telephone number, a call occurs. This call often goes undetected by the phone's owner. Some phones are more prone to this phenomenon than others.

Recordings involving cellular telephones or personal digital assistants (“PDAs”) are increasingly the source evidence in audio forensic examinations, compared to recordings originating with other devices such as hand-held digital recorders. On modern PDA cellular telephones recordings can be made either directly to the telephone or transmitted as voice mail messages. The current investigation focuses on differences in the two types of recordings in terms of dynamic range and linearity of levels. Such information can be important for characterizing the distance of sound sources relative to the microphone and are important for understanding transformation of recorded speech and non-speech sounds.
