Professional Audio Engineers, Audio Archivists, Ham Radio Operators, and Audiophile Hobbyists use our products for re-mastering, editing, noise removal and audio signal analysis. It is also used by many local, state, and federal government agencies including military intelligence operations for forensics law enforcement applications, particularly in surveillance situations. Private sector forensics audio engineers use it for post processing 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.
Here is a list of DC8's features:
Direct Spectral Editing
Diamond Cut's new Direct Spectral Editing mode allows you to directly manipulate your music files in the frequency domain. This works like a paintbrush on the sound. You can attenuate (erase) or amplify (highlight) selected areas of a file to eliminate things like coughs or squeaks without affecting the entire frequency range. For example, you could highlight just the 2000-3000Hz area of one word of a vocal performance to bring out the articulation of that word.
You can also use the DSE mode to interpolate selected frequency ranges or the entire spectrum using our new Frequency Domain Interpolation algorithm. This interpolation technique allows you to do much longer replacement than previously possible.
New in DC8.03 is more precise spectral displal settings. This allows you greater control over the levels and contrast of the spectral image.
Big Click Filter
The Big Click filter automatically detects and repairs clicks lasting much longer than the standard click algorithm. Clicks lasting 100's of milliseconds can now be effectively found and repaired automatically. The big click filter uses our new spectral interpolation algorithm for a dramatically better repair than you ever thought possible.
Overtone Synthesizer
The Overtone Synthesizer Filter generates an octave higher harmonics to add life to "dull" or limited bandwidth recordings. This effect is different and complementary to our VVA harmonic enhancer.
Sub Harmonic Synthesizer
The Sub Harmonic Synthesizer adds bass or sub-bass an octave below the exiting low frequencies. You can use it to add impact to almost any recording or to re-construct a lower octave that may have been missing in a restored original.
To see what can be done to an old cassette recording, listen to the following before and after recordings.

DVD Burner
DC8 Includes a DVD burner so you can burn CD's, DVD's or Blu-Ray disks to backup your work. The data burner works with ISO9660 or Joliet file systems and can burn Track-At-Once or Disk-At-Once modes with single or multi session disks.
Continuous Noise Filter with artifact suppression
The Continuous Noise filter is used for getting rid of constant background noise such as hiss and surface noise.
Our new technology reduces the aliasing and artifacting that sometimes affects the quality of the sound when you're pushing the Continuous Noise Filter to its limits. As you increase the power and amount of filtering on a tough file, in the past, you could generate new noise called artifacting. This machine-like ghosting was quite annoying and we'll be very happy to see it showing up much less in our restorations. Artifact suppression mode helps you push the Continuous Noise Filter harder without yielding these disturbing results!
The CNF filter also features an adaptive mode, This intelligent filter adapts itself to the changing nature of the noise in your file. As it gets smarter, your noise disappears.
Skin System
You can now change the overall appearance of DC8 to suite your mood or visual preference. We have included the ability to use the Windows Skins to change the style of the various screen elements that make up visual style. We have included a base set of styles and you can add your own.
DC Tune Library Database
This is cool new feature that increases both the power of DC8 and the uses for the product. The Tune Library is a database view that now lets you store, audition, and catalog your entire collection...all within the familiar confines of DC8. You can build playlists, burn CDs, track every single audio file on your computer...without ever having to copy it to one folder! It supports MP3, WMA, FLAC, Ogg Vorbis and your wave files all in the same environment and makes it easy to organize your entire portfolio of audio.
Best of all you can play all of your music through any of DC8's filters or effects without going into waveform editing mode. With DC8 you can now play, or shuffle playback all files thru the multifilter with a different preset for each tune.
Virtual Phono Preamp
This novel new approach to RIAA equalization offers more accuracy and better sound to any record type. The Virtual Phono Preamp works great in conjunction with our flat phono preamps and offers you the best possible approach and most accurate EQ ever developed for vinyl restoration. This powerful new approach also includes a 3-band EQ, gain adjustment, balance controls and a 30 Hz Rumble filter to make recording your files a breeze...no matter what setup you present to DC8.
The Multi-Filter with LIVE Feedthrough
You can select multiple different filters (up to 20) to apply to your audio in one filter pass. You can apply click and hiss removal to clean up your file and then, in that same session, add some reverb and equalization to enhance your final product. This is a great time saver because you can handle many tasks in one single pass through your audio.
You don’t need to necessarily have your audio recorded to the hard drive to take advantage of the numerous features of DC8. Live mode allows you to run dirty audio in the inputs of your sound card, set up your numerous filters on the screen and have cleaned audio flow out the output of your sound card in real time.
EZ Clean
One click noise reduction. Even the most inexperienced user can clean their treasured vinyl and tape recordings with one click of the mouse. DC 8 includes a powerful new automated system that seeks and destroys clicks, pops, hiss, hum and other disturbances common to older recordings.
Easy DeClick and DeCrackle
This is an "easy to use" click and pop noise reduction filter. I works great on all but the most difficult material and has been optimized to find the most common types of impulsive noises. With DC8 you can also remove Big Clicks in one pass with the Ez Declick filter.
For DC7, we improved just about every facet of our Impulse filters and you'll notice enhancements down the line with every slider you move...but most importantly, we've added a new checkbox that makes special consideration for brass and strong vocal passages that used to confuse the filters and remove good audio. With this new enhancement, you can push the Impulse filters to new heights and achieve even better results over competing products.
Punch And Crunch
This cool feature is a four band dynamic expander (punch) and compressor (crunch). It is a great method for breathing new life back into recordings or mastering your own recordings to sound best on the radio. This has been enhanced in Version 7 with an additional band (4 instead of 3), variable frequency crossover points and symmetrical slope crossovers.
Variable Frequency Mode allows you to move around the crossover frequencies with your mouse and Symmetrical Third Order Crossovers improve the selectivity of the filter
This filter is also very effective and bringing out vocal from a noisy recording. Its dynamic nature make it easier to use than a traditional compressor/expander.
Narrow Crackle Filter
Many times during restoration, you come across tiny clicks that lie just beneath the surface of your good audio that are hard to eliminate with standard click removal techniques. We saw these lemons and made lemonade with our new Narrow Crackle Filter. After the Standard or Easy Impulse filters have done their jobs, a new step will be the Narrow Crackle Filter that cleans up the minute clicks you used to have to live with.
Stretch And Squish Redesign
For DC7 we upgraded our compression and expansion filter Now you can make major changes to both speed and pitch of your audio files with no discernable difference in quality. Where the old time compression expansion tool was effective with only about a 10% increase or decrease in speed, you'll be amazed with what you can achieve using the new guy. Even if you've never used this tool before, you must try it...if nothing else but for the "giggle factor"
Spectrogram View
Used to be, you had to be a Forensics specialist and pay $1400 to get the Spectrogram view in your audio restoration. No more. The spectrogram view is sort of like an X-ray for sound. Sometimes stray clicks and pops can hide within the standard Time Domain View that you're used to seeing with virtually every audio editor. The Spectrogram let's you peer into the Frequency domain in a way you've never seen before. Those hidden clicks stick out like a sore thumb in the Spectrogram.
Full Support for popular file formats
DC8 has added full support for Ogg-Vorbis, FLAC and Broadcast wave to our existing support of Wav, WMA and MP3
CD Burner
Improved for DC8, we have a full featured Audio CD burner. Your can burn Disk-At-Once or Track-At-Once disks including support for CD Text writing. You can make CDs with our Easy to use Drag and Drop System our use the DC Tune Library.
You can also import WLS, XML or M3U playlist formats into the DC Tunes Library.
EZ Enhancer
One stop quick and easy enhancement plus tone controls . Even though this filter is easy to operate, don't be fooled. We have combined our best enhancement techniques into one filter with a bunch of presets and a very simple set of controls. This should be your first stop for putting the finishing touches on your restorations.
Better yet, use this filter Live in the Multifilter while playing back Tunes from the DC Tune Library.
Virtual Valve Amp lifer Enhanced
Many folks prefer the sound of tubes. The VVA is a tube simulator that allows you to re-create the sounds of many popular tube preamplifiers of the past.
For DC7 we added a new High Noise Suppression mode to aid in enhancing noisy recording plus added New Pentode 6267-EF86 Tube and MOSFET 2SK-175 transistor types.
Using the FAT BASS section of the Virtual Valve Amplifier, you can build up weak or inadequate bass lines in your favorite tunes and get those floors rattling again.
Dynamics Processor
This is a complete compressor, expander and noise gate in one filter. We have Increased Range of Attack and Release for a much better Noise Gate
CD Ripper
- Directly Convert your CDs to MP3, Ogg, FLAC or WAV files (New for DC8)
- Automatically look up CD information from the internet
- Optionally Rip All Files to One Track for easier for processing full CDs worth of material.
- Added flexible file naming for creating meaningful file names on your tracks.
- Added adjustable Rip speed limiting for better more accurate transfers.
- Automatically adds DC3V2 MP3 tags to ripped files.
Change sample rate and bit depth on any file.
Make Waves
Create waveforms from sub bass to supersonic, you can create waveforms for effect or audio measurements with the "Make Waves" generator. Great for testing your audio system or your hearing.
New in DC8 is the ability to save and recall presets like all of our standard filters. We have added dozens of presets already.
Standard Filters (LP, HP, BP,Notch)
Record from any input your system supports and Easily navigate to your sound card's mixer to adjust input levels on recording.
The wave file format has a 2 gigabyte limit. For those of you recording long radio shows or other events, this can be a real problem. Not with DC8 Though we can't fix the problem for Microsoft, we can find a nifty way of working around it. As we approach the limit, we simply stop the recording and open a second file. You get your whole recording...just split into several files.
Batch Editor with Auto Leveling
Got a bunch of files of varying volumes that you'd like to make into a CD? No problem, just go into our Batch File editor and tell it to Auto Level these files. The Auto Leveler will raise the level or normalize all of the files so that your CD level will not fluctuate during playback.
10 and 20 Band Graphic EQs
The standard equalizer filter in both 10 and 20 bands. Another powerful and easy to use enhancement and noise reduction tool.
Reverb
Yes real reverb...
Echo Effect
The Echo Effect contains two independent delay lines, which can be used in a number of different modes providing it with a great deal of flexibility compared to the old analog systems. Because it performs its function utilizing digital techniques, it does not suffer from the noise and distortion buildup associated with the older analog systems.
DeClipper
Very often, files will become “clipped” if the input on the sound card is turned up too high and the sound card is overloaded. The results are usually distortion and a waveform that is “flattened out” on top. The new DeClipper helps remove this distortion and reform the waveforms.
Fast Multi-Tiered Editor
There are two modes of graphical editing, the Classic mode and the Fast Edit mode. The Fast Edit mode of operation allows instant editing with each level saved in the Fast Edit History Window, so instant undo over numerous levels is easy. Cut/Copy/Paste instantly…regardless of file length.
Right Mouse Button "Preview from Here" for quick preview without zooming around
Output VU Meters
Two 100 segment VU meters can be displayed which will indicate the output of any filters that are being used. These meters indicate the level of the left and right channels and have both average and peak reading ballistics.
Direct X Support
Now you can use your favorite DirectX plug-ins within the DC8 operating system. You can even use them in the DC8 Multi-Filter.
Multi-Codec Sensor Support
DC8 automatically scans your system for Codecs and adjusts to whichever ones you have installed on your machine.
AVI Audio Support
Many of our customers wanted the ability to open an AVI file and extract the audio for editing. Many of our customers will now be happy! You can play an AVI within DC8, you can select an area and extract the audio.
More Presets
Now over 1270 Included!
Important Note: Most of the algorithms used in DC EIGHT and DC LIVE/Forensics use double precision floating point math as opposed to fixed precision integer math in order to minimize the possibility of introducing digital noise 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.
