HTML Attribute for <EMBED ...>
HIDDEN =FALSE |TRUE

HIDDEN indicates if the embedded object is visible or not. FALSE is the default.

This Code Makes This
<EMBED 
 SRC="/sounds/helloo.wav"
 HEIGHT=60 WIDTH=144
HIDDEN=TRUE
 >
(embedded object is not visible)
<EMBED 
 SRC="/sounds/helloo.wav"
 HEIGHT=60 WIDTH=144
HIDDEN=FALSE
 >
<EMBED 
 SRC="/sounds/helloo.wav"
 HEIGHT=60 WIDTH=144
 >
<!-- this example doesn't 
use HIDDEN at all -->

(same as TRUE)

The first example results in an unusable object because the user cannot start it in any way. However, if we add the AUTOSTART attribute, we get an invisible "background sound".

This Code Makes This
<EMBED 
 SRC="/sounds/helloo.wav"
 HEIGHT=60 WIDTH=144
HIDDEN=TRUE
