21: Audio Enhancement – Compression

Thursday, May 28th, 2015

21: Audio Enhancement - CompressionAs an Audio Forensic Expert, knowing what tools are available for audio enhancement and how they work is extremely important. While compressors are often thought of as tools for music production, they serve many functions in the Audio Forensic world. Like with most audio signal processors, it takes training and experience to operate compressors properly and effectively when enhancing audio.

When an audio enhancement is required, the recorded signal is often very low, or the desired source is unbalanced, with other signals in the recording. Compressors can increase the gain of a recording while also balancing the levels of the sound sources. While different compressors will vary, most have the same basic controls. These include the threshold, attack, release, ratio and makeup gain.

It is easy to focus on raising the level of the desired signal with a compressor and produce a loud, but unintelligible work product. Sometimes a smaller amount of compression may have a more positive effect on the audio. An experienced Audio Forensic Expert will know how to effectively clarify the recording based on his or her knowledge of audio and signal processing.

Now listen in with Audio and Video Forensic Expert Ed Primeau as he discusses the use of compressors in forensic audio enhancements.

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 professionalism.read 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 $750.00.read 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
