Muddled audio is not the end of the line!

Have you ever listened to a voicemail that you couldn’t understand because of how poor the quality was? Or have you ever wished you could get rid of that annoying lawnmower in the background of your video? Audio of many kinds have the ability to be enhanced which can then become a strong asset in court. From phone audio to dash cam audio, digital forensics experts can improve the integrity and authenticity by enhancing the audio files to serve as strong and reliable evidence in a court of law. 

Digital forensics experts have the ability to enhance anything from smartphone audio, deposition videos, digital handheld and pocket recordings, voicemail messages, dashcams and more. Once they have these audio files, they then have a number of ways to improve the overall integrity and authenticity of the file. Digital forensics experts are able to isolate one person's voice and increase the volume and clarity so that their voice can be heard, as well as minimizing any excess noise in the background of the audio such as trucks, lawnmowers, etc. They can also improve the quality by removing any clicking or drops in the audio in order to provide as close to seamless audio as possible.    

A key part of the audio enhancement process is to listen to the full audio multiple times before tweaking anything in order to diagnose where the problems lie. This is generally called critical listening and while it may seem trivial, it is actually an extremely useful tool for any analyst. From there, the files can be run through a program with tools to enhance the audio and the analyst can begin to clean up audio by removing any impurities throughout it. The analyst can dive deeper in the process through specific enhancements, whether it be dialogue isolation or removal of excess noise. Once finished, the enhanced file will be saved and sent through the proper channels back to the client for further use.
