General Information

Sources have no input but output a signal to be used elsewhere in the system. The output block size, number of channels, and sample rate are constructor arguments. They can be entered manually in the module properties, but will default to those of the system input pin if left empty. If a source module is used within a subsystem then the properties of the source module will be based on the first input pin of the subsystem. The parameters of the source can be changed at runtime via its inspector.

Warning: Sources are often very loud (0 dB) and must be followed by a scalar to reduce the level.

The following source modules are available in the Source folder:

	SineGen	Sine wave generator with no smoothing
	SineSmoothedGen	Sine wave generator with smoothing
	Source	Continuously copies data from internal buffer to output wire
	DCSource	Continuously outputs DC value to output wire
	ImpulseSource	Periodically outputs an impulse; period specified in samples
	ImpulseMsecSource	Periodically outputs an impulse; period specified in msec
	PeriodicSource	Continuously outputs a stored array of data. The internal buffer length is specified by module properties.
	PulseGen	Generates periodic rectangular pulse, with period and on time specified in msec
	Randi	Generates slowly varying random noise with linear interpolation between sample values
	Sawtooth	Generates a sawtooth wave (ramps up linearly from 0 to 1, then repeats) with specified frequency
	WhiteNoise	Generates uniformly distributed white noise
	PinkNoise	Generates pink noise by applying an IIR filter to internally generated white noise
	Oscillator	Generates oscillations with specified frequency and start phase
