In 2006 several of the audio enhancement tools previously only available in the DC-Art line were trialed and released as VST plugin devices for use in other VST plugin compatible audio software. These plugins included a suite of powerful digital signal processing (DSP) audio tools including the Automatic Frequency Domain Filter (AFDF) as well as the Virtual Valve Amplifier (VVA). These tools were readily welcomed especially the AFDF due to its ability to automatically adapt itself to noisy files and remove large amounts of noise with little intervention from the user. The AFDF filter found its application in situations where voice recordings were obscured by noise and needed to separated from cacophonous environmental sounds in order to make them audible and understandable. This was primarily because it was designed as an “Adaptive” filter that constantly changed during operation, adjusting itself to the noisy environment. Unlike other filters offered in the DC-Art range, the AFDF is optimized for Forensics recordings and not “High Fidelity” files. As such, it was programmed to exhibit a faster response time and a narrower effective bandwidth while producing higher levels of noise reduction at the expense of potentially producing higher levels of digital artifacts. Applications included recordings collected by law enforcement officials and others responsible for cleaning up poorly recorded evidence in a short time for accurate presentation at trials.
