Forensic Audio and Video Enhancement

More often than not, audio and video evidence is not clear enough to accurately hear and view the events as they occurred. This is where an expert can assist the trier of fact by performing forensic audio and video enhancement. By performing audio and video enhancement of the evidence, the forensic expert can help the court better see and hear the original events as they occurred.

What is Forensic Audio Enhancement?

Forensic Audio and Video EnhancementAudio enhancement is the process of clarifying audio recordings to increase intelligibility. One of our most common forensic audio enhancement investigation goals is to increase dialogue intelligibility also known as voice enhancement.

Processing techniques must be applied to unwanted noises like static, HVAC fans, hums and other distracting sounds first. These distracting noises are also known as “unwanted sounds”.

Once the unwanted sounds have been reduced or removed, then enhancement processes can be applied. These enhancement processes will increase the “desired sounds” and overall voice quality and dialogue intelligibility.

The same is true for the audio portion of a video recording. Even video recordings may need audio enhancement. For more information visit how to enhance audio in a video file. 


What is Forensic Video Enhancement?

Forensic Audio and Video EnhancementForensic video enhancement is the process of clarifying the events using non-destructive techniques in order to preserve the quality and integrity of the pixels. Clarifying or enhancing the events as they occurred assists the trier of fact to make determinations about the events. 

Surveillance video recordings used as evidence can be enhanced regardless if they were recorded during the day or at night. The success of the forensic video enhancement is directly proportionate to the enhancement techniques, resolution and frame rate of the video evidence.

As video forensic experts, we perform forensic video enhancement services on a daily basis. A video forensic expert is the most qualified professional to enhance events as they occurred naturally. This is due to the fact that we understand how the images were captured, and what processes can be applied without altering the events. Often times, we are also asked to provide forensic image enhancement for identification purposes.

We use basic software tools such as Adobe Premiere as well as advanced enhancement techniques to enhance or clarify video recordings to use as evidence. Enhancement is a more common word outside of the courtroom, whereas clarification is used in the courtroom. We create customized filtering to sharpen the video image and remove noise. This improves the identification and enhancement of the images in the CCTV Surveillance video recordings.

Video Enhancement Process 

It’s common for us to perform a preliminary analysis to ensure we are confident in meeting our client’s expectations. This process requires one hour of our lab time, in order to apply test enhancements. Once we are confident we can assist, we then enter a full investigation where we can create derivative video exhibits and demonstrative video exhibits. These demonstrative video exhibits include motion-based highlighting and/or circling, as well as speed reduction. 


Client Reviews

As a business owner myself, I am aware of the effort it takes to assemble a team of employees that conduct their business as if it were their own, and take pride in how they represent your company to others. As an owner who feels has achieved that status myself, I immediately recognize it in others. I must say that this is not common in the workforce today. From the first contact with your company, through closeout, every one of your employees made this experience a pleasure and acted with the upmost more

I received credentials from two technicians, then a third person ended up doing all the work and kept in touch with me by e-mail. I never saw any proof that the work was done and they told me they found nothing. They could not tell me what was making the noise or the lights. A waste of $ more

Excellent work. Primeau took a low light camera recording of vandalism at my home and converted the video to images that we used to identity the vandals. Additionally, Primeau was able to identify characteristics of the vandals car that were used for a positive identification. Services were efficient, timely, and professionalread more

Ed and his team are great! I took in footage of my boyfriends dog being stolen and they were so willing to take every step possible to enhance the video to retrieve the information we needed. The resolution on our camera/video wasn't great (our fault, not theirs) and they were unable to get the information we needed BUT they guided me in the next steps to take. Thank you guys!!read more
