Microsoft.DirectX.DirectSound

Microsoft DirectSound provides a system to capture sounds from input devices and play sounds through various playback devices using advanced 3-D positioning effects, and filters for echo, distortion, reverberation, and other effects. The following tables list the members exposed by the Microsoft.DirectX.DirectSound namespace.
