Media_ListSoundOutputFormats gives you a list of the available output formats.
No parameter is used.
If you are giving users the option to select from all possible output formats, a useful technique is to create two fields: a calculation text field equal to this function, and another text field to be used as the selection field. Set the selection field to display a popup menu value list that is generated by the calculation field.
