This is the dialog box where you define which type of ".wav" file the prompter will produce. You can choose between 8 and 16-bit files and sample rates from 6 to 48 KHz. If you don't know where to start select 16-bit files at 22 KHz, and go from there.
Browsing buttons allow you to select the script file that will be used for the next prompter session as well as the target directory where the recorded prompts will be saved. If you don't enter a "save-to" path in the prompter defaults then the complete path with file name (without extension though, it is always ".wav") has to be entered in the script file itself. If a save-to directory is entered in the prompter defaults only a file name (without extension) should be entered in the script file.
The prompter parameters can also be set as system defaults through the Tools/Defaults menu so that next time you use the prompter the same selections will be presented as defaults.
