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 audio and video forensic expert can help. By enhancing the evidence, the forensic expert can help the court better see and hear the original events as they occurred.

Forensic Audio Enhancement


Forensic Audio Enhancement is the process of removing unwanted noise and increasing the intelligibility of the desired sound source. No two recordings are exactly the same and therefore there is no one way of performing an audio enhancement. We combine our extensive knowledge of audio with specialized training in forensic enhancement techniques to achieve the best results possible. Audio forensic examiners and experts at Primeau Forensics have been trained in and use the latest tools and techniques to enhance audio evidence while maintaining the integrity of that evidence.

Some of the time, Primeau Forensics is asked to prepare a forensic transcript to accompany the enhanced audio. This helps the court better understand the dialogue being spoken in the audio evidence that is difficult to hear. Our critical listening skills are key when completing an accurate forensic transcript.

Forensic Video Enhancement

Video enhancement is also a strategic process that requires experience. With the digital era of  forensic video evidence, playback of forensic video evidence can be a challenge. Various digital file formats, as well as storage issues can surface very quickly. Primeau Forensic’s video forensic examiners keep up with the latest updates to forensic software as well as digital media formats to make sure your video evidence can be used in the litigation process.  The first step is to load the video evidence into one of our forensic computers, either MAC or PC (depending on the evidence format). The video forensic expert or examiner begins the enhancement process by first viewing the entire video to determine the series of events that need to be more clear so the court can better see the events as they occurred.

Some of the time, the video can be slowed down and enlarged for easier viewing. Sharpening tools and other types of shadow and highlight filtering that is accepted in the scientific community are applied to make the series of events more clear. Frames are often exported and turned into digital still images, then clarified outside the video environment. This helps the court identify persons or other events in the video that are hard to see in the video format, especially when difficult playback issues arise.
