Setting up LiveAudio plug-ins

Audio files can be handled by the QuickTime, LiveAudio, and Real, plug-ins. Which plug-in is used depends on which Mime type has been mapped to it. For information on setting up Real audio files, see Click the Real tab in the Plug-in Inspector..

For information on setting up the Basic, More, and Attribs tabs for an audio plug-in, see Setting up plug-ins.

To set up the Audio tab for a plug-in:

1 Click the Audio tab in the Plug-in Inspector.

2 Select Is Mastersound to group sounds using the Name attribute assigned on the More tab and to define one sound of this group as the Mastersound. (All sounds within a group must have the same Name, but only one sound within the group can be defined as the Mastersound.)

This feature is useful if you want to design your own console using the button elements from the standard console. Rather than having to place several EMBED actions on a page (for PLAY, PAUSE, STOP, and VOLUME controls, for example), each of which would control the same sound and each of which would require loading the same sound, you can group sounds using the Name Attribute and define one sound within the group as the Mastersound. The audio plug-in then accepts the Mastersound and ignores all the other sounds in the group. Thus you can use the different audio controls attached to the different sounds in the group to control the single Mastersound without having to load all of them.

3 Select Autostart to play the audio as soon as the viewer opens the page.

4 Select Loop to play the audio in an endless loop. Enter a number in the Loop text box to specify the number of times the audio should loop. If you leave this text box blank, the audio will play endlessly.

5 Enter a time period in minutes and seconds in the Starttime text box (using the format mm:ss) to set the start time of the audio.

6 Enter a time period in minutes and seconds in the Endtime text box (using the format mm:ss) to set the end time of the audio.

7 Type a value in the Volume text box to set an audio volume. The value must be an integer from 0 (mute) to 100 (full volume). If this text box is left blank, the volume is set to 100.

8 From the Controls pop-up menu, select the controls to be provided with your media clip:
