Audio-Video Identification is an advanced forensic discipline that deals with the examination of voice recordings, CCTV footage, videos, and digital media for authenticity and identification purposes. Experts analyze whether an audio or video recording is original or has been altered, edited, manipulated, or tampered with. Voice comparison involves the study of speech patterns, waveform analysis, spectrographic examination, pitch, and frequency characteristics. Video examination includes frame-by-frame analysis, enhancement, synchronization, facial comparison, and detection of editing or deepfake manipulation. Audio-video forensic analysis is widely used in criminal cases, cybercrimes, blackmail investigations, sting operations, surveillance matters, and media disputes. The integrity and authenticity of digital recordings are essential for their admissibility in courts. Scientific examination helps investigative agencies verify evidence and establish the identity of speakers or individuals appearing in recordings.
