PLAYING SOUNDS
- sound is included in a web page, or as part of a web page
Inline Sound
- Inline sound can be added to a web page by using the <bgsound> element or the <img> element.
PLAYING SOUNDSUsing A Helper (Plug-In)
- A helper application (Plug-In) is a program that can be launched by the browser to "help" playing sound.
- Helper applications can be launched using the <embed> element, the <applet> element, or the <object> element.
- can let some (or all) of the player settings be controlled by the user.
PLAYING SOUNDSUsing The <bgsound> Element
- The purpose of this element is to provide a background sound for a web page:
<bgsound src="beatles.mid" />
PLAYING SOUNDSUsing The <bgsound> Element
<html><body><h2>Music In The Background</h2><bgsound src="beatles.mid"></body></html>
Example
PLAYING SOUNDS
Using The <img> Element
-The purpose of this element is to embed multimedia elements in web page:
<img dynsrc="horse.wav" />
PLAYING SOUNDS
Using The <img> Element
<html><body><h2> Horse As An Image</h2><img dynsrc="horse.wav"></body></html>
Example
Using The <embed> Element

Using A Hyperlink
<a href="beatles.mid"> Click here to play the Beatles </a>
- If a web page includes a hyperlink to a media file, most browsers will use a "helper application“ to play the file.
<html><body><h2>Linking To Beatles</h2><p><a href="beatles.mid">Click here to play the Beatles</a></p></body></html>

MEDIA PLAYER REFERENCEWhy Has the class ID Changed?
- The correct class ID for Windows Media Player 7 and later is: clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6.
- Many places on the internet it states that the class ID should be: clsid:22D6F312-B0F6-11D0-94AB-0080C74C7E95. This class ID is not the correct one, but it will work, because of backward compability..
