    About the Product (Overview)


    DCArt10.9x and DC Forensics Audio Laboratory v.10.9x contain a comprehensive set of tools designed for audio restoration, enhancement audio archiving, audio signal analysis and audio surveillance. This extensive toolkit will allow the user to remove extraneous noise and also enhance the sound from any audio source without degrading the content contained on the original. Recognizing that there is a tradeoff between the degree of noise removed from a source and the fidelity, transient and frequency response maintained, we have sought to provide the highest level of user control while maintaining ease of use over the variables that affect the audio restoration and enhancement process. Thus, the slider controls have a very wide range of adjustability in order to cover the needs of any audio restoration or enhancement situation. Special “Green Zones” are provided on many of the slider which identify the range (or span) of the slider controls which have the highest probability of producing nominally good results. Some filters or effects have multiple modes of operation. In some cases, the Green Zones will change depending on your chosen mode of operation. However, there will be situations in which you will find yourself operating these controls beyond those zones. Look at it as a manifestation of the 80 – 20 rule. 80% of the time, you will find your desired setting inside the Green Zone, but 20% of the time, it may fall below or above that zone. Operating outside of the Green Zones is okay if you are satisfied with the results produced. So, the Green Zones are a great place to start with when tackling a project using any particular filter or effect. Another place to look for a good starting point are within the descriptive factory presets presented for each Diamond Cut Productions filter or effect.

    A Typical Filter showing “Green Zones” for Slider Controls

    Professional Audio Engineers, Radio and Television Engineers, Forensic Scientists, Audio Archivists, Ham Radio operators, Recording Studios and Audiophile hobbyists use our products for re-mastering, editing, noise removal, signal enhancement and audio signal analysis and/or synthesis. It is also used by many local, state, and federal government agencies including both military intelligence operations and forensics law enforcement applications, particularly in surveillance situations. Private sector forensics audio engineers use it for post processing and authentication of forensic recordings of phone calls and surveillance tapes. Radio and television networks have found the LIVE (real-time signal processing) feature of particular value in their real-time applications. Additionally, a number of Engineering Colleges and Universities use this software as part of the laboratory portion of some coursework pertaining to applied DSP techniques and Audio Forensics Science.

    Important Note: Most of the algorithms used in DCArt10.9x and DC Forensics Audio Laboratory v10.9x use double precision floating point DCArt10.9 internal math as opposed to fixed precision integer math in order to minimize the possibility of introducing digital noise or distortion into your .wav files. The tradeoff associated with using this method is the time required to process a file being slightly longer than the fixed precision integer method.
