class PHASEGroupOverview
With all the sounds it contains, a group shares settings like gain, playback rate, mute, and solo. Groups are nonhierarchical and don’t overlap — that is, each sound event associates with only one group.
Apply Group Settings to Sounds
You can apply settings to the sounds a group contains. For instance, an app can share volume settings with various sound effects and dialogue audio groups. The following example creates a group for background audio, such as environmental sound layers played with ambient music. By interpolating the group’s gain setting, the audio fade applies to every sound in the group.
