Detailed Description

This component uses the Enlightened Sound Daemon (ESD) system to provide soundcard output functions. The component accepts integer raw audio messages (16 bit native endian) and does not generate any messages itself.

Member Function Documentation

bool MIPEsdOutput::close

(

)

This function closes the previously opened soundcard device.

bool MIPEsdOutput::open	(	int	sampRate,
		int	channels,
		int	sampWidth = 16,
		MIPTime	blockTime = MIPTime(0.020),
		MIPTime	arrayTime = MIPTime(10.0)
	)

With this function, the soundcard output component opens and initializes the soundcard device.

Parameters:

sampRate	The sampling rate.
channels	The number of channels.
sampWidth	The width of a sample in bits.
blockTime	Audio data with a length corresponding to this parameter is sent to the soundcard device during each iteration.
arrayTime	The amount of memory allocated to internal buffers, specified as a time interval. Note that this does not correspond to the amount of buffering introduced by this component.
