Digital Voice Recorder Enhancement and Noise Reduction

Enhancement of digital audio from a small hand held digital voice recorder is similar to the cassette tape method. The audio is cloned from the recorder and put into the forensic audio computer. Noise removal filters and enhancement techniques are applied and then the inteligibility is increased.

More and more people are turning to the digital voice recorders for anything from domestic problems, surveilance and interogation of witnesses. Although they can be superior in quality if used properly than audio cassette most people still do not adjust them for the best possible audio signal. In most cases the recorder was placed in a bad location and voice activation was used as well as a low bit rate. All of these factor in and can cause improper signal to noise ratios.
