Audio forensics is a branch of forensic science that involves close analysis of audio files. After acquiring a file, audio forensic experts work through a series of audio forensic services to confirm the recording’s quality and understand its contents. The examination involves practices such as transcribing dialogue, improving speech clarity, and reconstructing event timelines based on the information presented.
Once an expert examines an audio file, it’s typically used as admissible evidence in a court of law. An audio forensic analysis can be significant in court, whether as a part of a simple civil case or criminal investigation. Our experts have processed over 5,000 audio, video, and image forensic investigations and provided expert testimony in over 500 cases in local, state, and federal courts. Our experienced audio, video, and image forensic lab can help you decipher the content into meaningful data by providing expert reports that are both easy to understand and court-friendly.

AUDIO FORENSIC ANALYSIS SERVICES
Authentication is vital for identifying whether the audio evidence was tampered with. The authentication process often happens when determining the chain of custody, but this isn't an absolute determiner. During the rest of the analysis process, audio and video forensics experts can decide if a file was edited.
Forensic audio transcription is the process of converting an audio file into written words. This conversion is completed by a forensic expert under controlled conditions with an enhanced audio recording.
Voice comparison, or speaker recognition, is the analysis of known and unknown voice samples within audio evidence. This procedure is used to confirm or eliminate an individual as the speaker.
