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

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

this code	produces this
<EMBED SRC="../graphics/sounds/helloo.wav" HEIGHT=60 WIDTH=144 HIDDEN=TRUE >	(embedded object is not visible)
<EMBED SRC="../graphics/sounds/helloo.wav" HEIGHT=60 WIDTH=144 HIDDEN=FALSE >
<EMBED SRC="../graphics/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	produces this
<EMBED SRC="../graphics/sounds/helloo.wav" HEIGHT=60 WIDTH=144 HIDDEN=TRUE >	this page

See the page on background sounds for more details on the best way to put background sounds on your web page.
