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 IDirectSound3DBuffer interface method. However, applications often must set or retrieve all the values at once. You can do this with the IDirectSound3DBuffer::GetAllParameters and IDirectSound3DBuffer::SetAllParameters methods.
