volume (cast member property)
Syntax

the volume of member
whichCastMember
Description
Shockwave Audio (SWA) cast member property; determines the volume of the specified SWA
streaming cast member. Values range from 0 to 255.
This property can be tested and set.
Example

volume (sound channel)
Syntax
sound(
whichChannel
).volume
the volume of sound
channelNum
Description
System property; determines the volume of the sound channel specified by
channelNum
. Sound
channels are numbered 1, 2, 3, and so on. Channels 1 and 2 are the channels that appear in the Score.
The value of the
volume
sound property ranges from 0 (mute) to 255 (maximum volume). A
value of 255 indicates the full volume set for the machine, as controlled by the
soundLevel
property, and lower values are scaled to that total volume. This property allows several channels to
have independent settings within the available range.
The lower the value of the
volume
sound property, the more static or noise you’re likely to hear.
Using
soundLevel
may produce less noise, although this property offers less control.
This property does not support dot syntax. Use the syntax exactly as shown here.
