Save As...

  Choose Save As...  from the File menu to save a DECsound file
  under a new name.  DECsound displays the Save File dialog
  box, which lists all the .AUD files in your current directory.
  When you save a DECsound recording under a new file
  name, the new file name becomes the current file name.
  Choosing Save As...  from the File menu to save a recording
  under its existing name is the same as choosing Save As...

  from the File menu.
