The following is a list of new features contained in CALSOD 3.10 compared to the original release of CALSOD 3.00 in 1993. Note that some of these features were introduced into various minor releases of CALSOD 3.00. However, the last four new features listed here are only available in CALSOD 3.10. Please check the contents of the README.DOC file that was provided with the version of CALSOD 3.00 that you received to see what additional features have been added to this release of CALSOD 3.10.
- Provision for using a user-defined text editor (subject to memory limitations).
- Ability to exit to DOS from within CALSOD.
- Support for LMS measurement files, with example files.
- Support for CLIO measurement files, with example files.
- Support for AMS-PC measurement files, with example files.
- Support for AIRR measurement files, with example files.
- Support for PC AudioLab measurement files, with example files.
- More design equations for active filters.
- Function keys have been added to the CALSOD editor to speed up exiting the editor and recalculating system transfer functions. For example, if you now press the F6 key while in the editor, this automatically saves the file that is being edited, exits the editor, recomputes all system transfer functions, and activates the plot selection menu. This feature significantly speeds up the edit/plot cycle that is part of working with CALSOD.
- The first few lines of each data file are now displayed when the file selection window is active, together with the file's size and time/date stamp. This makes it much easier to recognize files by their contents, especially if descriptions are placed at the top of each file.
- File names shown in the file selection list box can now be selected by pressing the key corresponding to the first letter of the file name. Doing so now scrolls the highlight bar to the first file whose name starts with that letter, and pressing the same letter again causes any subsequent files starting with that letter to be highlighted.
- Extra target functions are provided for Bessel lowpass filters.
- Sound pressure and impedance plots can now be displayed simultaneously.
- The default colors of the lines used in plotting response functions can now be configured by the user.
- An option has been added to allow the default text colors to be set.
- If enabled, the plot title is now always displayed at a fixed location at the bottom of the plot and is always visible.
- A clock display has been added to the editor, in keeping with the clock display available on CALSOD's main screen.
- Cable inductance effects can now be included in the models used to determine Thiele-Small parameters from measurements of driver impedance.
- The input voltage can be allowed to vary during the circuit optimization. This can result in a better match between the target function and the computed optimized response.
- The target observation point (when only one is specified) and input voltage can be selected to be displayed over each plot.
- A new IAC submodule has been added which allows the inductor dcr to be automatically calculated for air-cored coils made from copper wire. The user can specify the wire diameter or SWG. The inductor dcr is allowed to vary during the optimization, by-passing the need for manual changes at the end of each optimization cycle.
- The SPK submodule has been expanded to permit driver time delays to be specified.
