14.6. Controlling FlashCom Audio
Problem
You want to control the volume
and pan of audio attached to a movie
clip with the attachAudio( )
method.
Solution
Create a Sound
object
that targets the movie clip to which the
sound is attached and use the pan and volume methods of the
Sound class.

or from a net stream) can be heard once it has been attached to a
movie clip using the attachAudio( )

control the playback (stopping, starting, or seeking) of an attached
FlashCom sound, you can control the volume and panning with a
Sound
object that targets the movie clip to
which the sound has been attached:
// Attach audio (which can be either local microphone data or a net stream) to a
// movie clip.
mySoundHolderMc.attachAudio(Microphone.get( ));
// Create a Sound
object that targets the movie clip to
// which the sound has been attached.
mySound = new Sound(mySoundHolderMc);
// Control the sound using the Sound class's get/set methods as you would normally.
// Shown here is an example that sets the volume.
mySound.setVolume(60);
Warning
Early revisions of Flash Player 6 had a bug that prevented you from controlling attached sounds in this way. This technique requires Flash Player 6.0.60.0 or later. Not only should you update your plugin Player but also the Test ...
