Adobe Director Basics

ADOBE DIRECTOR BASICS
Audio mixers and sound objects
Creating a new sound object
You can create a new sound object in two different ways:
Use the [+] button in the Audio Mixer Inspector. See “Adding a sound object to a mixer” on page 407 for details
Use the mixer.createSoundObject() method
Sound object methods
Use the following methods to modify the sound object:
soundObject.moveTo(): moves the sound object to a different mixer
soundObject.replaceMember(): changes the cast member audio source
Note: In Director 11.5.8, soundObject.replaceMember() fails unless a second parameter with the value
[#loopCount: 0] is used. This will lead to the sound repeating continuously. There are also issues with setting
soundObject.loopCount = 1. If you want to change the sound member without looping the sound forever, the simplest
workaround is to use a handler like the one below.
on ReplaceSoundObjectMember(aSoundObject, aMember)
vName = aSoundObject.name
vMixer = aSoundObject.mixer
vFilterList = aSoundObject.filterList
vMixer.deleteSoundObject(aSoundObject)
vSoundObject = vMixer.createSoundObject(vName, aMember)
vCount = vFilterList.count
repeat with ii = 1 to vCount
vFilter = vFilterList[ii]
vSoundObject.filterList.append(vFilter)
end repeat
return vSoundObject
end ReplaceSoundObjectMember
Note that this code will replace any customized values for the properties of the sound object with default values. You may
need to use a similar technique to the one used for audio filters to transfer the custom property values from the old sound
object to the new one.
Use the following methods to control playback of a sound object:
soundObject.breakLoop()
soundObject.mute()
soundObject.pause()
soundObject.play()
soundObject.seek()
soundObject.stop()
soundObject.unmute()
Use the following methods to save the sound object to a file on a local drive:
soundObject.save()
soundObject.startSave()
soundObject.stopSave()
