Minimum and Maximum Distance Values

Applications can specify minimum and maximum distance values for a 3D sound buffer. The minimum distance is the distance at which the sound does not get louder. Conversely, the maximum distance is the distance at which the sound no longer attenuates. For more information about the relationship between these values, see Minimum and Maximum Distances.

An application sets and retrieves the minimum distance value by using the IDirectSound3DBuffer::SetMinDistance and IDirectSound3DBuffer::GetMinDistance methods. Similarly, it can set and retrieve the maximum distance value by using the IDirectSound3DBuffer::SetMaxDistance and IDirectSound3DBuffer::GetMaxDistance methods.
