Streaming linked Shockwave Audio and MP3 audio files

Director streams sounds that have been compressed with Shockwave Audio as well as MP3 audio
files, from either a local disk or a URL. Before you can set up a streaming Shockwave Audio cast
member, you must create a Shockwave Audio or MP3 file.
To create external Shockwave Audio files, do one of the following:
•
In Windows, select Xtras > Convert WAV to SWA, and select the WAV files to convert.
•
On the Macintosh, use the Peak LE 2 software to export Shockwave Audio sounds.
For both methods, the audio settings are similar to those for using Shockwave Audio to compress
internal sounds. For more information, see
Shockwave Audio" on page
Note: Converting WAV to SWA does not compress IMA compressed sounds.
To stream a linked Shockwave Audio or MP3 sound:
Select Insert > Media Element > Shockwave Audio.

This process creates a cast member that controls the streaming Shockwave Audio.
In the SWA Cast Member Properties dialog box that appears, click Browse and select a

Shockwave Audio file on a local disk, or enter a URL in the Link Address text box.
Unless you select a file in the same folder as the movie, the movie always links to the exact
location that you specify. Be sure to link to the correct location.
Set the remaining cast member properties in the Property inspector, as described in the
3
following list:
To set the volume of the sound, use the Volume slider in the SWA tab in the Property
inspector.
To select the sound channel for the sound, select a number from the Channel pop-up menu
in the SWA tab. To avoid potential conflicts, select Any, which causes the sound to play in
the highest numbered available sound channel.
To specify the size of the stream buffer, use the Preload option in the SWA tab. Director
attempts to load enough sound data to play for the specified time in seconds. This prevents
gaps in sounds that play over slow or interruption-prone Internet connections.
