NAudio.Wave.Asio Namespace Reference

Classes
struct	Asio64Bit
	ASIO 64 bit value Unfortunately the ASIO API was implemented it before compiler supported consistently 64 bit integer types. By using the structure the data layout on a little-endian system like the Intel x86 architecture will result in a "non native" storage of the 64 bit data. The most significant 32 bit are stored first in memory, the least significant bits are stored in the higher memory space. However each 32 bit is stored in the native little-endian fashion. More...
struct	AsioBufferInfo
struct	AsioCallbacks
	ASIO Callbacks. More...
struct	AsioChannelInfo
	ASIO Channel Info. More...
class	AsioDriver
	Main AsioDriver Class. To use this class, you need to query first the GetAsioDriverNames() and then use the GetAsioDriverByName to instantiate the correct AsioDriver. This is the first AsioDriver binding fully implemented in C#! More...
class	AsioDriverCapability
	AsioDriverCapability holds all the information from the AsioDriver. Use AsioDriverExt to get the Capabilities. More...
class	AsioDriverExt
	AsioDriverExt is a simplified version of the AsioDriver. It provides an easier way to access the capabilities of the Driver and implement the callbacks necessary for feeding the driver. Implementation inspired from Rob Philpot's with a managed C++ ASIO wrapper BlueWave.Interop.Asio http://www.codeproject.com/KB/mcpp/Asio.Net.aspx. More...
class	AsioException
	ASIO common Exception.
class	AsioSampleConvertor
	This class stores convertors for different interleaved WaveFormat to ASIOSampleType separate channel format.
struct	AsioTime
struct	AsioTimeCode
struct	AsioTimeInfo

Enumeration Type Documentation

AsioError

enum NAudio.Wave.Asio.AsioError

ASIO Error Codes.

Enumerator
ASE_OK	This value will be returned whenever the call succeeded.
ASE_SUCCESS	unique success return value for ASIOFuture calls
ASE_NotPresent	hardware input or output is not present or available
ASE_HWMalfunction	hardware is malfunctioning (can be returned by any ASIO function)
ASE_InvalidParameter	input parameter invalid
ASE_InvalidMode	hardware is in a bad mode or used in a bad mode
ASE_SPNotAdvancing	hardware is not running when sample position is inquired
ASE_NoClock	sample clock or rate cannot be determined or is not present
ASE_NoMemory	not enough memory for completing the request

AsioMessageSelector

enum NAudio.Wave.Asio.AsioMessageSelector

ASIO Message Selector.

Enumerator
kAsioSelectorSupported	selector in <value>, returns 1L if supported,
kAsioEngineVersion	returns engine (host) asio implementation version,
kAsioResetRequest	request driver reset. if accepted, this
kAsioBufferSizeChange	not yet supported, will currently always return 0L.
kAsioResyncRequest	the driver went out of sync, such that
kAsioLatenciesChanged	the drivers latencies have changed. The engine
kAsioSupportsTimeInfo	if host returns true here, it will expect the
kAsioSupportsTimeCode	supports timecode
kAsioMMCCommand	unused - value: number of commands, message points to mmc commands
