Diamond Cut DC7 - The full story

Note: DC7 requires Windows XP SP2 or Windows Vista (any version)

Diamond Cut DC7 is a dramatic leap forward in audio restoration effectiveness. We have increased the performance of just about all of our filters and added a few new ones. In addition we have added the new DC Tune Library to help you organize your restorations and music files plus much more.

Artifact Suppression In Continuous Noise Filter

This 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!
New Tune Library Database View
This is cool new feature that increases both the power of DC SEVEN 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 DC SEVEN.  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 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 DC7's filters or effects without going into waveform editing mode
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 DC SEVEN.
Narrow Crackle Filter
We love new tools...especially tools that cover a category that wasn't covered before.  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.  
Impulse Filter Enhancements
We've 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.
Stretch And Squish Redesign
Our time compression and expansion filter has been upgraded in the same way you blink your eyes and your Ford Taurus becomes a Mustang Fastback!  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 Now Included
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.  "Come out, come out, where ever you are!"

And here are the rest of the features from that are carried over from previous versions of DCart

The Multi-Filter

You can select Multiple different filters to apply to your audio in one session.  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.
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 SEVEN 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.
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.
Direct X Support
Now you can use your favorite DirectX plug-ins within the DC SEVEN operating system.  You can even use them in the DC SEVEN Multi-Filter.
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.  
Adaptive Filtering Added To Continuous Noise Filter
This intelligent filter adapts itself to the changing nature of the noise in your file.  As it gets smarter, your noise disappears. 
CD Database Integration
If you're working with CDs, DC SEVEN will instantly dial up the Internet CD Database and assign the names to all of your tracks before you rip them. This will save you the time of doing a Save As when you name the files.
No Time Limits
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 DC SEVEN.  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. 
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 DC SEVEN, you can select an area and extract the audio.
Fat Bass
Using the FAT BASS section of our Virtual Valve Tube Simulator, you can build up weak or inadequate bass lines in your favorite tunes and get those floors rattling again.
10 and 20 Band Graphic EQs
Another powerful and easy to use enhancement and noise reduction tool.  
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.
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. 
Multi-Codec Sensor Support
DC SEVEN automatically scans your system for Codecs and adjusts to whichever ones you have installed on your machine.
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. 
LIVE Feedthrough Mode You don’t need to necessarily have your audio recorded to the hard drive to take advantage of the numerous features of SIX.  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. 
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.
