[2] Unlike other programs in the field of record and audio restoration, DC-Art has undergone regular and significant modifications on an almost annual basis.

Unlike previous versions, DC-Art Millennium brought with it a new level of performance and features in the audio restoration and enhancement software market.

[6] Unlike other software of its type it included features like live feed-through mode whereby a user could effectively restore a recording on the fly.

In addition, DC-Art Millennium boasted over 15 real-time tools that could be used individually or in combination (called a multi-filter) and thus setting the restoration software benchmark for its time.

In August 2001, DC-Art Live and Millennium were up-dated to version 4.8 with various bug fixes and the addition of a digital high resolution VU meter.

As the name suggests, Audio Mentor was designed to take novice users "by the hand" and guide them through the restoration process of removing clicks, pops, hiss and surface noise from any recording format.

In a rather innovative method, Audio Mentor took a user through a series of informative steps from setting the recording levels, noise reduction, sound enhancement to making a CD in minutes.

This period saw a significant change to how the various software algorithms were being performed and resulted in increased speed of filter processing (reportedly anywhere from 25 to 100% faster).

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.

DC-7 also introduced a simple "Tune Library" which allowed a user to catalogue the progression and restoration of audio files in a database style view.

Somewhere along the line it was also decided to include the Spectrogram View previously only found in the DC-Forensics range with the basic audio restoration/Live software version to aid in manual impulse noise removal and other challenging operations.

Together, these changes provided very successful and popular in the field of audio restoration tools and was likened to the transition "from regular television to High Definition".

Due to a number of significant changes to the core of the program, rigorous beta testing took several months delaying the final release to March 2010.

DC8 also introduced the concept of a Direct Spectral Editor tool to provide users with the ability to manually attenuate or interpolate very long-lived noise events on recordings like coughs, whistling, chair movement and other unwanted spurious signals.

The Virtual Phono Preamplifier was also expanded to include 49 additional LP EQ recording curves usable with either RIAA or Flat Preamp front-end hardware.

These two filters generate harmonic frequencies to re-create the lost lower and upper octaves of a recording improving the fidelity of a restoration.
