public sealed class BassWasapi

Public NotInheritable Class BassWasapi

The BassWasapi type exposes the following members.

	Name	Description
	BASS_WASAPI_CheckFormat(Int32, Int32, Int32, BASSWASAPIFormat)	Checks if a particular sample format is supported by a device (endpoint) in exclusive mode.
	BASS_WASAPI_CheckFormat(Int32, Int32, Int32, BASSWASAPIInit)	Checks if a particular sample format is supported by a device (endpoint).
	BASS_WASAPI_Free	Frees the Wasapi device/driver (endpoint).
	BASS_WASAPI_GetCPU	Retrieves the current CPU usage of BASSWASAPI.
	BASS_WASAPI_GetData(IntPtr, Int32)	Retrieves the immediate sample data (or an FFT representation of it) of the current Wasapi device/driver (endpoint). This overload uses an IntPtr to reference the buffer data.
	BASS_WASAPI_GetData(Single, Int32)	Retrieves the immediate sample data (or an FFT representation of it) of the current Wasapi device/driver (endpoint). This overload uses a managed float[] to reference the buffer data as 32-bit!
	BASS_WASAPI_GetDevice	Retrieves the Wasapi device setting in the current thread.
	BASS_WASAPI_GetDeviceCount	Returns the total number of available Wasapi devices (endpoints).
	BASS_WASAPI_GetDeviceInfo(Int32)	Retrieves information on a Wasapi device (endpoint).
	BASS_WASAPI_GetDeviceInfo(Int32, BASS_WASAPI_DEVICEINFO)	Retrieves information on a Wasapi device (endpoint).
	BASS_WASAPI_GetDeviceInfos	Returns all available Wasapi devices (endpoints).
	BASS_WASAPI_GetDeviceLevel	Gets the audio meter information of the current Wasapi device/driver (endpoint).
	BASS_WASAPI_GetInfo	Retrieves information on the Wasapi device being used.
	BASS_WASAPI_GetInfo(BASS_WASAPI_INFO)	Retrieves information on the Wasapi device being used.
	BASS_WASAPI_GetLevel	Retrieves the level (peak amplitude) of the current Wasapi device/driver (endpoint).
	BASS_WASAPI_GetLevel(Single, BASSLevel)	Retrieves the level of the current Wasapi device/driver (endpoint).
	BASS_WASAPI_GetLevel(Single, Single, BASSLevel)	Retrieves the level of the current Wasapi device/driver (endpoint).
	BASS_WASAPI_GetMute	Gets the mute status of the current Wasapi device/driver (endpoint).
	BASS_WASAPI_GetVersion	Retrieves the version number of the basswasapi.dll that is loaded.
	BASS_WASAPI_GetVersion(Int32)	Retrieves the version of the basswasapi.dll that is loaded.
	BASS_WASAPI_GetVolume	Retrieves the current volume level.
	BASS_WASAPI_Init(Int32, Int32, Int32, BASSWASAPIInit, Single, Single, WASAPIPROC, IntPtr)	Initializes a Wasapi device/driver (endpoint).
	BASS_WASAPI_Init(Int32, Int32, Int32, BASSWASAPIInit, BASSWASAPIFormat, Single, Single, WASAPIPROC, IntPtr)	Initializes a Wasapi device/driver (endpoint) in exclusive mode.
	BASS_WASAPI_IsStarted	Checks, if the current Wasapi device/driver (endpoint) has been already started (via BASS_WASAPI_Start).
	BASS_WASAPI_Lock	Locks the device to the current thread.
	BASS_WASAPI_PutData(IntPtr, Int32)	Adds sample data to an output device buffer ("push" device).
	BASS_WASAPI_PutData(Single, Int32)	Adds sample data to an output device buffer ("push" device).
	BASS_WASAPI_SetDevice	Sets the device to use for subsequent calls in the current thread.
	BASS_WASAPI_SetMute	Sets the mute status of the current Wasapi device/driver (endpoint).
	BASS_WASAPI_SetNotify	Sets a device change notification callback.
	BASS_WASAPI_SetVolume	Sets the volume of the current Wasapi device/driver (endpoint).
	BASS_WASAPI_Start	Starts processing the current Wasapi device/driver (endpoint).
	BASS_WASAPI_Stop	Stops the current Wasapi device/driver (endpoint).
	FreeMe	Unloads this library. This must be called when you have previously called LoadMe.
	LoadMe	Loads this library into memory. The library will be search in the current application directory.
	LoadMe(String)	Loads this library into memory. The library will be loaded from the given path.

	Name	Description
	BASSWASAPIVERSION	Current BASSWASAPI version (without minor revision).

BASSWASAPI is basically a wrapper for Windows Audio Session API drivers, with the addition of channel joining, format conversion and resampling.

BASSWASAPI requires a soundcard with a Windows Session API drivers installed (Vista or above). It also makes use of SSE2 and 3DNow optimizations, but is fully functional without them. BASS is not required by BASSWASAPI, but BASS can of course be used to decode, apply DSP/FX, etc.
