After 35+ years of experience testifying as audio expert witnesses and consultants, our lead forensics expert Edward Primeau has worked with and learned from some of the greatest trial lawyers in the world. This experience has strengthened Primeau Forensics’ expert witness performance in the court room. We have testified in local, state and Federal courts all over the USA and worked with lawyers around the world.



When it comes to testifying, the forensic expert and client attorney spend as much time as necessary to prepare. Every time we testify, we bring a list of questions to review with our client attorney as a foundation for our litigation support and preparation time together. Not only does this save the attorney time but it helps them to better understand how to present the facts from the forensic investigation when testifying.


Nothing solidifies integrity better than a humble, third party, unbiased approach to a case. The experts at Primeau Forensics are investigators, technicians and scientists first, expert witnesses second. Our favorite part of expert witness testimony is explaining the relevance of the forensic analysis to the trier of fact. Lastly, our experts are all properly qualified under Federal Rule 702 for expert witness testimony.


We understand that the deposition process is designed to gather information from us that may be presented in court. Our experts at Primeau Forensics are thick skinned and know how to calmly answer the questions they are asked. We know how important it is to simply answer the question instead of over answering or trying to follow the thought process of the deposing lawyer.

Before we enter a deposition, there are a few requirements our experts must meet with our client attorneys. We always discuss the facts from our report and other facts in the case that we should be aware of (like other expert deposition testimony). Another requirement and arguably most importantly anticipated direct examination questions the deposing lawyer will ask. 

Our deposition preparation meetings range anywhere from two to six hours. Dependant on the type of magnitude of the case (criminal vs civil).


When under oath, the audio expert witness has sworn to speak accurately and truthfully. Much like a deposition, courtroom testimony can be an intense situation for an expert. Our experts understand the process of direct and cross examination. When we prepare for testimony, we anticipate all questions that will be asked of us during direct and cross examination. 

Educating the tier of fact is most important to our experts, so that the scientific analysis is understood in a simply yet compelling way.  Our approach is to present the analysis in common sense plain English. At Primeau Forensics, we believe that audio expert witness testimony begins with an in-depth forensic investigation. It is our opinion that every forensic investigation should be processed as if it were going to trial. 

Our team of experts provide expert audio testimony when the investigation has a rock-solid scientific foundation. For the expert witness testimony to be successful, our experts must remain unbiased throughout the investigation, as well as in the courtroom.

One great trial lawyer had this to say about our lead expert witness, Ed Primeau:

Ed Primeau is the best at what he does! As a trial attorney, I depend on experts to educate me in the relevant field for which they are hired. My focus has always been on finding an expert who not only simplifies the subject area, but is also creative in approach. 

I recently had a case in which I needed an audio and video forensic expert. I found Ed. Ed is a genius and was absolutely amazing in front of the jury.
