Batch Parameters for 3-D Buffers

Applications can retrieve or set a 3-D sound buffer's parameters individually or in batches. To set individual values, your application can use the applicable IDirectSound3DBuffer8 interface method. However, applications often must set or retrieve all the values at once. You can do this with the IDirectSound3DBuffer8::GetAllParameters and IDirectSound3DBuffer8::SetAllParameters methods.

Parameter changes can also be made more efficiently by flagging them as deferred and then executing them all at once. For more information, see Deferred Settings.
