What is Audio & Video Forensic Authentication?
Audio & Video Forensic Authentication is the technical examination of recorded audio and video to assess characteristics relevant to authenticity, integrity, alteration, processing, continuity, and other forensic questions.
Can you detect whether an audio recording has been edited?
Forensic examination can look for technical characteristics or anomalies that may be consistent with editing or alteration. However, the ability to reach a conclusion depends on the quality, format, source, and condition of the recording.
Can you authenticate CCTV footage?
CCTV footage can be examined for relevant technical characteristics, including file properties, continuity, frame sequences, encoding, metadata where available, and other indicators. The scope depends on the original CCTV system and the files supplied.
Can you examine a WhatsApp or social media video?
A supplied copy can be examined, subject to its technical condition. However, platforms may recompress or transform uploaded media, so the original source file is preferable whenever available.
Can deleted portions of an audio or video recording be recovered?
Recovery depends on how the file was created, stored, deleted, overwritten, processed, and supplied. In some cases, additional forensic data recovery may be technically possible, but it cannot be guaranteed.
Can you enhance unclear audio?
Where technically feasible, audio processing may improve the audibility or intelligibility of relevant portions. Enhancement cannot reliably recreate information that was never captured by the original recording.
Can you enhance CCTV or video footage?
Certain image-processing techniques may improve visibility or assist examination of relevant frames. The extent of improvement depends on the original resolution, compression, lighting, focus, movement, and quality of the recording.
Do you need the original recording?
The original or earliest available source is generally preferable because subsequent copying, conversion, compression, editing, or messaging-platform processing can alter technical characteristics.
