Audio forensic investigation is the nearby assessment of sound records for legitimate purposes. In a forensics laboratory, audio forensic experts examine the recording to verify its authenticity. Improving speech clarity, transcribing dialogue, comparing voices, and reconstructing event timelines are all common components of the examination.
Let us look at the process of an audio forensic expert:
The custody chain
To answer questions about the source of the audio evidence and how it was handled from creation to delivery to the courtroom, the chain of custody must be examined. A chain of custody log, which increases the authenticity of the file, may be kept by law enforcement. To maintain consistency and accuracy in the chain of custody, an audio forensic expert must document file retrieval with video recordings and images.
Call for the original
The earliest or original copy of the audio file may be requested by a forensic audio expert. For authenticity, an exact copy of the digital original file can be made. It is impossible to precisely copy the original file if it was stored on analog media.
Reciprocal retrieval
An expert must retrieve an audio file in a way that keeps it as close to how it was when it was created. A forensic image of the storage medium or original file, the original recorder, or a file transfer from the original storage medium is among these methods for retrieval.
