Public Properties

	Name	Description
	Complex	Set this property to true, to request computation using complex numbers.
	DeviceIndex	Returns the index of the currently open CoreAudio driver in the list of available drivers.
	DisabledOrDisconnected	Returns true, if the hardware appears disabled or disconnected.
	IsDouble	Set this property to false, to request computation in 32bit floating point precision, 64bit, if true.
	Items	Default array property allows access to individual list items.
	Items	Default array property allows access to individual list items
	Items	Access TSignal objects by Index.
	Paused	Set this property to True, to pause the playback and/or recording.
	ProcessingTime	Returns processing time of the real-time loop in miliseconds.
	Volume	Set this property to to change the playback/recording volume.

Published Properties

	Name	Description
	Active	Set active to false to suppress the propagation of the Pull request and the subsequent call to the Update method.
	ChannelCount	Set this property to the channel count to be used for playback and/or recording.
	ChannelCountHw	Set this property to the channel count to be used for playback and/or recording on the device.
	ChannelMapping	Allows the component to feed more or fewer channels than the hardware count.
	Continuous	If True, the component will pass on the udpate request to the connected component.
	DesiredLatency	Specify desired latency in miliseconds.
	EditIndex	Specifies index of the item in the list for which to display the design-time editor.
	ExtendedBufferTime	Specifies the size of extended playback and recording buffer in miliseconds.
	FloatPrecision	Set this property to request computation in 32bit/64bit precision with real/complex numbers.
	FloatPrecisionLock	Set this property to true to lock changes to FloatPrecision property.
	Inputs	Data source.
	OnAfterUpdate	The event is triggered after the call to the Update method.
	OnBeforeUpdate	The event is triggered just before the call to the Update method.
	OnBufferSkipped	Triggered when the extended buffer is too small.
	OnDisplayUpdate	The event is triggered after the OnAfterUpdate event.
	OnNotifyUpdate	The event is called after a call to InternalUpdate, OnAfterUpdate and OnDisplayUpdate from within the Update method.
	OnParameterUpdate	The event is triggered when ParamUpdate method is called.
	OnProcessRealTime	Request for new data.
	OnStart	Triggered when the playback/recording is about to start.
	OnStop	Triggered when the playback/recording is about to stop.
	OutputBuffers	Currently active output buffers.
	Precision	Storage format of the input stream (not hardware).
	PrecisionHw	Storage format of the hardware stream.
	PullInterval	Longest interval between pull requests in miliseconds.
	Ripple	read FRipple write SetRipple;
	SamplingFrequency	Specifies the desired sampling frequency.
	SettingsWin	This is SettingsWin, a member of class TSignalCoreAudio.
	SuspendNotifyUpdate	Set this property to True, to prevent calling OnNotifyUpdate from the Update Method.
	TransBW	read FTransBW write SetTransBW;
	UseMessagesForBuffering	Set to false when using PullBuffers.
