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.

Classes

AccessDeniedException The request failed because access was denied.
AllocatedException The request failed because resources, such as a priority level, were already in use by another caller.
BadFormatException The specified wave format is not supported.
BadSendBufferGuidException The globally unique identifier (GUID) specified in an audiopath file does not match a valid mix-in buffer.
Buffer Contains methods and properties used to manage sound buffers.
Buffer3D Contains methods and properties used to retrieve and set parameters that describe the position, orientation, and environment of a sound buffer in 3-D space.
BufferDescription Contains properties and methods that describe the characteristics of a new buffer object.
BufferLostException The buffer memory has been lost and must be restored.
BufferTooSmallException The buffer size is not large enough to enable effects processing.
Capture Contains properties and methods used to create sound capture buffers.
CaptureAcousticEchoCancellationEffect Represents a DirectSound capture effects object used to set and retrieve parameters on a capture buffer that supports acoustic echo cancellation. This object requires Microsoft Windows XP or later.
CaptureBuffer Contains properties and methods used to manipulate sound capture buffers.
CaptureDevicesCollection Represents a collection of DeviceInformation structures for each available capture device.
CaptureNoiseSuppressEffect Represents a DirectSound capture effects object used to set and retrieve parameters on a capture buffer that supports noise suppression. This object requires Microsoft Windows XP or later.

DSoundHelper Contains helper methods and fields for DirectSound.
EchoEffect Represents a DirectSound effects object used to set and retrieve effect parameters on a SecondaryBuffer object that supports echo.
EffectsUnavailableException The effects requested could not be found on the system, or they are in the wrong order or in the wrong location; for example, an effect expected in hardware was found in software.
FlangerEffect Represents a DirectSound effects object used to set and retrieve effect parameters on a SecondaryBuffer object that supports flange.
FullDuplex Represents a full-duplex stream.
GargleEffect Represents a DirectSound effects object used to set and retrieve effect parameters on a SecondaryBuffer object that supports amplitude modulation.
