Detailed Description

This component allows sound to be captured on Win32 and WinCE platforms. It uses the MS-Windows Multimedia SDK waveIn... functions. This component should be used at the start of a chain: it accepts only MIPSYSTEMMESSAGE_WAITTIME messages. The messages generated are raw audio messages, containing 16 bit signed little endian data.

bool MIPWinMMInput::close

(

)

This function closes a previously opened sound capturing device.

bool MIPWinMMInput::open	(	int	sampRate,
		int	channels,
		MIPTime	interval = MIPTime(0.020),
		MIPTime	bufferTime = MIPTime(10.0),
		bool	highPriority = false,
		UINT	deviceID = WAVE_MAPPER
	)

This function opens the sound capturing device.

Parameters:

sampRate	The sampling rate (e.g. 8000, 22050, 44100, ...)
channels	The number of channels (e.g. 1 for mono, 2 for stereo)
interval	The sampling interval.
bufferTime	The component allocates a number of buffers to store audio data in. This parameter specifies how much data these buffers can contain, specified as a time interval.
highPriority	If true, the thread of the chain in which this component resides and a background thread in which the sampling takes place will both receive the highest priority.
