Video and audio forensics

Media forensics focuses on acquisition, analysis, and presentation of audio, video, or photographic evidence.

Media forensics focuses on acquisition, analysis, and presentation of audio, video, or photographic evidence. Free or inexpensive software tools available to the public make it easy for a novice to manipulate audio or video recordings to make them appear very different from their original content. When audio and video evidence is presented in a court of law, the authenticity is almost always challenged. This can be the difference between whether it is admitted or dismissed.

Coalfire Labs utilizes state of the art technological solutions to conduct the most thorough examinations of audio and video recordings, as well as photographic images.  Audio and Video recordings have a unique quality to them. Unlike other forms of evidence, audio and video recordings allow the viewer to visually see, or audibly hear, the events as they transpired. However, there are instances where the audio or video recordings contain too much noise, or interference to clearly see or hear the events. Shadows, extreme sunlight, and other factors can make it difficult to see what’s important. Enhancement can commonly remove those barriers and make the image easier to distinguish. In instances where a person’s voice is low and hard to hear, it’s possible to enhance the frequency range of the voice and make it more audible. Examination of photographic images can reveal vital information such as the location where the image was taken, as well as other additional information.

Our experts are trained to examine the evidence, verify its integrity, and when needed, enhance the recording or image to more clearly identify that vital piece of evidence.  Our team has worked for law enforcement, defense attorneys, and commercial entities enhancing and authenticating surveillance and covert (“hidden camera”) videos, still images, telephone audio (call recordings), and “crowd-sourced” mobile and video evidence.
