In order to investigate and settle legal, criminal, or civil problems, video and audio forensics examines, analyzes, and interprets video and audio recordings using scientific methods. Videos and audio recordings used as evidence in court trials are authenticated and examined using this branch of forensic science.
An examination of a video's authenticity, a determination of whether it has been changed or manipulated, and the extraction of pertinent data from the video, such as the identification of people or automobiles, are all examples of video forensics. Aspects of audio forensics may include voice identification, audio augmentation, and voice recognition in addition to authenticating and analyzing audio recordings to see whether they have been tampered with.
Some of the techniques used in video and audio forensics include:
- Enhancement of the video and audio for better recording quality and analysis
- Image and audio analysis to identify and extract information
- Authentication of video and audio recordings to determine their origin and authenticity
- Comparison of video and audio recordings with known samples to identify individuals or match recordings
- Timestamp and geolocation analysis to determine when and where a recording was made
Video and audio forensics plays a crucial role in investigations, helping to provide evidence that can be used in court and assist in the resolution of legal disputes.
