Why use an expert for Audio Enhancement Services?

In contrast, the alternative to an audio expert is an audio engineer or someone with training in audio analysis. Although these individuals may be knowledgeable, their approach is mainly subjective, whereas an expert applies an objective process that prioritizes evidence integrity.  Furthermore, an expert is qualified to ensure the admissibility of the clarified exhibit in a court of law.

    Working with Mike and his team at Primeau Forensics was a five-star experience from beginning to end. First, their cost estimates were accurate. And the costs overall were well worth the excellent services and deliverables received. The team worked overtime over a holiday weekend to meet some of our unexpected needs. Mike testified in the trial of our case and was a stellar witness. Communication was good. I would give them six stars if I could!

    We were in a bind on the eve of trial and contacted Primeau Forensics a few days before the we were to start. Mike worked tirelessly, even late at night and over the weekend to get us what we needed and based on his representations and expert opinions we successfully won our issue before the Court and proceeded to trial with one less issue to worry about. I can’t state enough about how satisfied we are with the service, attention and result we received. We definitely will be using this group in the future.

Audio Formats We Can Enhance

Advanced audio recorders can be used in remote areas, like phones, tablets, or hidden recorders. However, when these recordings are placed poorly in an environment with noise, they introduce issues. Therefore, a qualified expert can fix these issues using repeatable methods for courtroom use. 

Forensic Audio Enhancement Methodology

Audio enhancement is the processing and filtering of audio recordings to improve the signal quality and intelligibility of the signals of interest, such as speech, by attenuating noise or otherwise increasing the signal-to-noise ratio. Standard Terminology for Digital and Multimedia Evidence Examination (astm.org)

Evaluation

First, we decide if the recording is good enough to use enhancement techniques. Evaluation is critical to use our client's money wisely.

Identification

Secondly, we identify and reduce undesired sounds such as hissing, humming, static, clipping, sirens, wind, HVAC, and other broad-spectrum noises in the recording.

Reduce/Remove

Thirdly, we apply forensic techniques to improve the quality of the recording. Furthermore, the technician, analyst, or expert must document the potential court use process.

Enhancement

Fourth, we increase the wanted signals. in most cases, the audio signals in the human speech frequency range or voice enhancement.

Expert Reporting

Most importantly, processes applied are documented for repeatability and admissibility under expert testimony requirements.

Verification

Finally, an Audio Forensic Expert reverse-engineers and verifies the investigation to ensure the recording is accurate.

Voice Enhancement

For example, this advanced tool maintains the atmosphere of a recording to amplify the speech. Overall, it is designed to divide dialogue from environmental sounds like pedestrians, cars, walking, climate, or other sounds.

ECHO-CANCELLATION

Our advanced tools provide echo cancellation, which reduces reverberance. Specifically, this process is most effective on recordings created in larger spaces where echo limits speech intelligibility.

Noise Reduction

An expert reduces unwanted sounds with a noise profile, which is called noise reduction or background noise reduction. Most importantly, this process does not affect important signals like dialogue.

audio authentication

Critical Listening

Critical listening is the cornerstone of audio forensics because audio experts are trained as audio engineers first. Therefore, audio experts have highly trained ears that can pick up crucial audio sections that need to be enhanced.

Equalization (EQ)

Equalization is a process that reduces unwanted frequencies and enhances needed ones. For instance, with distracting frequencies reduced/removed, audio enhancement experts can perform other procedures smoothly.

Dynamics Processing

Traditionally, compressing the sound raises the volume levels and balances them for clarity. Therefore, experts may use compression and gates to boost the sound and reduce any remaining unwanted noise.
