Audio Enhancement

Audio Forensics evidence can have its fair share of problems. It is not uncommon for an audio evidence file to have some sort of volume or clarity issues. When these types of events occur audio, enhancement is needed to help resolve these types of issues. The first stage in the enhancement process is to determine the audio evidence’s signal-to-noise ratio. Where the audio’s signal is desired speech or events, and where noise is any unwanted sounds. If the audio’s signal is greater in volume than the noise signal, enhancement is possible. Our audio forensics experts can help reduce/remove those unwanted sounds by processing the audio forensics evidence with the listed services below.
