There are many components, departments, etc involved in crime investigation. Forensic audio analysis allows investigators to examine and understand types of sounds -- such as recordings -- from a particular crime scene. Audio forensics is an important part of any investigation.
The analysis of forensic sound has many different components. One of the most important jobs is to make sure the sound is authentic. A sound analysis must make sure a recording hasn't been altered with or tampered from its original state. It must be evaluated to make sure it is okay to be used in a courtroom.
State of the art equipment are used to authenticate an sound recording. Although many question this process, validating the sound may be done in multiple ways. With an excellent ad skilled personnel or engineer and hi tech equipment, tamperings are identified in the clip if present. This new technology allows for authenticating to be done in alternative ways, though it is currently under scrutiny.
The process of enhancing a recording involves "cleaning" it -- clearing away static and other unwanted noises. The point of enhancing is to carefully uncover the evidence in the recording without accidentally destroying it. It is also possible to "reverse engineer" a noise in a recording in order to help determine where exactly it came from.
Investigators must listen to people talking on the audio and transcribe the dialogue. They must determine who the people talking are. This can help them determine who was at the scene of the crime and provide any evidence. The crime scene is set up through sounds. The history of this analysis started with the Watergate Scandal that occurred in the 1970s. They used sound as evidence during the investigation and had to pick apart several sound recordings.
Because sound recording may come from different devices, a crime scene may involve many sound recording devices. Audio recordings are available from 911 calls, voicemails, and memory cards from mobile devices and computers. Consequently giving tons of clips to analyze. A forensics audio lab needs to be organized and thorough as they handle tons of recordings. Their work is crucial because a legitimate sound lab analyzes these recorded sounds and makes sure that they are permissible in court.
These forensic technicians are also often called upon to testify in court. When they are on the stand they have to defend their findings. It is therefore important to make sure their findings stand up under scrutiny.
Audio forensics is an important part of a crime investigation. Recordings might reveal who is at the scene of the crime and can help establish things such as motives and alibis. As new technology changes, advances in technology will be able to interpret sounds in different ways and do a better job of analyzing sound recordings. It is not an easy job, but it is an important part of trying to solve a crime investigation.
