This command allows selection of the default source conversion format and file open format. This is the source format that will originally be selected in the dialog boxes associated with file conversion or file open operations. Vox Studio does detect the input format if the necessary information is in the file header; otherwise it presents the format entered here as the default in Dialog boxes.
If you plan to manipulate many files, all in the same format, it makes a lot of sense to select this format here as the default. If you do not, you will need more manual intervention when you use Vox Studio. Selecting the right default here will make working with Vox Studio much more productive.
