How do I use the Reference Curve Editor in DNA?
DNA Reference Curve Editor
There are numerous examples of references curves, yet the most popular one is probably the 
equal loudness curves, see below.
DNA stores the reference curves in the DNA4/Weight directory as “CRW” files.
The files are defined using the Reference Curve editor from DNA (DNA4/RefCrv.exe) and placed on the graphs using the “Ref Curve” tab of the graph properties.
Working principle of Reference Curve:
- One curve is the reference, the others are derived from it.
- You can draw the curve by hand or adapt it by hand
- You can enter the values in a table
- You can copy and shift a curve
ICONS
Selection Icons 
- Selection » Select a point or a curve, black point indicates the curve is selected, empty larger square indicates the X value is selected.
- Select X »
Curve Icons 
- Add curve – allows you to add a curve parallel to the selected one, by clicking on the graph to attach it to a point. This continues until you select another button.
- Add point
- Delete point
When you want to delete for example a point of 100 Hz for all curves, use the combination with the X-selection as shown below:
Graph icons 
- Zoom all » Unzoom
- Zoom window » Select a portion to zoom in 2 directions
- Zoom X » only zooms the X-axis
- Zoom Y » only zooms the Y-axis
MENU
The standard MS Windows commands or those already mentioned as icons are not discussed here.
Edit Menu
- Select All » selects all points on a curve. Use this to move the complete curve.
- Edit numbers » edit numbers on each curve as well as the reference value.
- Graph Properties » Menu Also via “Right Click – Properties”
Tools Menu
- Offset » Move the curve up or down (negative value)
- X Axis Lin. <-> Log. » Toggles between linear and logarithmic X axis. It is recommended to do this before you start.
View Menu
This allows you to enter the Label (make sure to press ENTER or the value is not registered) and the Ref value.
If you click on a point on the graph or on the frequency arrows you will see the right screen. This does not allow you to change the values.
About the reference, you need to have all the values either in increasing order (top to bottom) or in decreasing order (reverse).
Example
The graph on the left has no reference curve, while the one below has the reference curve added.
