Using Lingo sound elements with RealMedia
All the Lingo elements in this section are documented in the main Lingo Dictionary and are
discussed here only as they pertain to working with RealMedia content. For complete
information, see the Lingo Dictionary.
Supported sound elements
The following Lingo elements operate on a sound channel and are fully supported for sound
channels playing the audio portion of a RealMedia cast member:
• isBusy()
• elapsedTime
• fadeIn()
• fadeOut()
• fadeTo()
• pan (sound property)
• soundBusy()
Although you can use the following Lingo elements with a RealMedia cast member, they cause
problems when used on a sound channel. For example, you can use
member("Real").stop()
but should not use
sound(whichChannel).stop() if the audio portion of a RealMedia cast
member uses whichChannel.
• member (sound property)
• pause()
• play()
• stop()
You can use the following property on a sound channel playing the audio portion of a RealMedia
stream but not directly on a RealMedia cast member. For example, you can use
sound(whichChannel).volume = 200, but not member("Real").volume = 200.
volume
You can set the system variable soundEnabled to FALSE to turn off RealAudio, but if you reset it
to
TRUE, you must also call the play command to resume playback.
