Forensic Audio
In the ideal world,every time you use a recording device the results would yield pristine audio. All speech would be clearly intelligible and your recordings would be immediately usable for their intended purpose. In the real world, however, often there are problems masking your audio such as background or street sounds, low recording levels, interference, buzz, hum and hiss. We have customized many filters to correct these problems often enabling the recordings to be used in court and for investigation.
The mission of a forensic audio laboratory is to provide audio evidence in criminal or civil investigations. On a day-to-day basis, a forensic audio laboratory will deal with sensitive law-enforcement recordings, 911 emergency calls, audio from mobile phones, DVD, video, CCTV, computers, solid-state devices, memory cards — in fact, just about every type of recorded audio media there is and has ever been. Many of the tasks will at some point involve forensic enhancement audio for use as evidence at trial. However, general advice and guidance concerning the correct capture and subsequent review of audio material is also essential. This provides what is commonly referred to as ‘best evidence’.
Ultimately, the responsibilities of the forensic audio laboratory are to present evidence that can be relied upon within a court of law. The role of a forensic audio practitioner is to serve the courts, as opposed to their tasking agency (ie. the prosecution or defense). This involves considerable audit of processes and procedures. Our work must remain repeatable by other forensic audio specialists. The responsibility of the forensic audio professional is to act with impartiality and integrity in the pursuit of justice for all.
Authenticity
In brief, this is the science behind establishing whether a recording is original and whether it has been tampered with, either maliciously or accidentally. This task is not performed by all forensic audio laboratories, and requires very specialist skills and equipment. Advances in new technologies are allowing alternative methods, currently under close scrutiny by the forensic audio world for dealing with digital audio.
