using sounds

[Kurt Kaufman]

"Do I still need to use a different app to
embed the sound in the stack?"

No; see the "import" command (in the docs) to import sounds under script 
control.  Otherwise, it is also possible to import via the Application 
Overview Window.  Sequence:
View > Application Overview > (NameOfStackFile) > (NameOfStack)  > 
(NameOfCard) > AudioClips .....then click on disclosure triangle in 
upper right corner of Application Overview Window.....THEN, click IMPORT.
