Two 100 segment VU meters can be displayed which will indicate the output of any filter or multiple filters that are being used by DC Forensics10 or DCArt10. These meters indicate the level of the left and right channels and have both average and peak reading ballistics. They are calibrated to indicate values from -60 dB to 0 dB, with 0 dB being full-scale output when operated in linear mode. The VU meters are calibrated to indicate -100 dB to 0 dB (with 0 dB also being full-scale output) when operated in log mode. The selection between linear and log modes is made via the “Edit/Preferences/General/VU Meter Scale” preferences tab. Any signal above the 0 dB level will be clipped by the system. Signals that are clipped are indicated by the illumination of a small red “LED” indicator at the top and in the middle of the meter display. The red clip indicator (at the top of the VU meter) trips on at signals above -1.0 dB (slightly lower than 0 dB).
Peak Hold
The VU meters includes two peak indicators. The white horizontal bar is designed to “hold” the indication of an overload for two seconds after it occurs so that it will be more obvious to you that a clipping event has occurred. The green horizontal bar is a peak hold indicator and will hold the value of the audio peak until such time as the reset button, located at the bottom of the VU meters, is activated by the mouse. These VU meters can be activated or de-activated under the View Menu. Also, they can be "dragged and dropped" anywhere on your desktop workspace using your left mouse button or docked and enlarged at the right or left hand margin of the software user interface. The right mouse button can also be used to “hide” or “auto hide” the VU meters.
Volume Control
This feature allows you to view and adjust the primary sound card volume controls. Three controls are presented:
- Main Volume Control
- Wave Volume Control
- Balance (between left and right channels)
Important Note:
This volume control is only useful for sound cards that make use of the Windows Mixer. For any sound card that doesn’t use the Windows Mixer, adjustment of volume will take place using the proprietary mixer provided by the manufacturer of that product.
Fast Edit History
When working in Fast Edit mode, this cool little panel on the left side of your screen is like having your own personal secretary. It keeps track of every edit and allows you to navigate quickly from one change to the other. If you decide to start at midpoint in this list and want to eliminate all edits done after this point, just double click on that edit and the system will ask if you’re sure…then eliminate all edits after that point. All of the data pertaining to the fast edit history profile are contained in .ses (session) files. These files are stored with your .pkfs (peak files) and can be deleted once you’ve finished with the file. Fast Edit temp files include elements of the source file name for ease of identification.
