Detailed Description

An Audio Generator node is a Generator that outputs audio data. It supports all Generator functions, and adds additional functions.

Function Documentation

XN_C_API XnStatus XN_C_DECL xnCreateAudioGenerator	(	XnContext *	pContext,
		XnNodeHandle *	phAudioGenerator,
		XnNodeQuery *	pQuery,
		XnEnumerationErrors *	pErrors
	)

Creates an audio generator.

Parameters:

pContext	[in] The context in which to create the audio generator.
phAudioGenerator	[out] A handle to the created audio generator.
pQuery	[in] Optional. Can be used to select which audio generator to create. If not specified, this function may create any audio generator that is available.
pErrors	[in] Optional. If provided, will be filled with information about audio generators that could not be created.

	)

Gets the current audio meta data.

Parameters:

hInstance	[in] A handle to the instance.
pMetaData	[in] The struct to be filled.
