Forensic audio enhancement services are the scientific process of clarifying audio recordings using non-destructive techniques to preserve speech quality. This is crucial for the trier of fact can make determinations about the events within the recorded evidence. Above all, the goal of forensic enhancement is to better hear dialogue by removing unwanted noise. This scientific process of improving the quality of dialogue is also known as speech enhancement or voice enhancement.


Audio Forensics Expert applies enhancement techniques to remove sounds like static, furnace and air conditioning fans, hums and other distracting sounds. Therefore, these distracting noises are also known as “unwanted sounds”. Then, once we remove the unwanted sounds, we can apply enhancement processes. These enhancement processes will increase the “wanted sound” like speech.

Our forensic audio experts apply enhancement services using industry-standard equipment that is also used by law enforcement. Above all, this is necessary to improve speech with forensic accuracy. Once the recording is enhanced, it can then be admitted as a clarified exhibit to assist the Trier of Fact.

Similarly, the same is true for the audio quality of a video clip. We also perform enhancement to the audio within video recordings like police dash cameras, body cameras, doorbell surveillance devices (CCTV). That is why we have additional information for your review here how to enhance audio in a video file.

Often times when a layperson processes an audio recording, these changes affect the recorded evidence in a negative way. For instance, the authenticity of the events change and an inaccurate representation of the events makes the recording inadmissible in court. This is oftentimes based on changes a nonqualified technician makes that alters the sounds in the recording.

A qualified forensic expert must follow the best practices established by the scientific community. This includes performing the audio enhancement services accurately, documenting the procedures used and presenting the findings to the Trier of Fact. In order to identify dialogue with accuracy, a successful enhancement or voice enhancement investigation is essential. Our expert witness testimony communicates these results in an accurate way to the Trier of Fact.

In conclusion, our client’s experience will experience how improved speech can assist the Trier of Fact in making determinations. Whether it be a smaller criminal case or a multi-billion dollar civil case. When audio recordings that are difficult to hear are enhanced forensically, they only help the litigation process.
