Public Member Functions
	Noise ()
	Constructs a noise generator. If no filter is used, the output will be white noise. By default, the output will be standard deviation = 1 noise, which clips the output for standard audio devices, so make sure the level is set properly.
	~Noise ()=default
Public Member Functions inherited from Siggen
virtual	~Siggen ()=default
void	setFilter (const std::string &name, std::shared_ptr< Filter > f)
	Set a filter on the signal. For example to EQ the signal, or otherwise to shape the spectrum. Filters are stored in a map, and setFilter can be used to overwrite them, if a null pointer is given.
void	setDCOffset (d offset)
	Set a linear DC offset value to the signal.
void	setMute (bool mute=true)
	Mute the signal. Passes through the DC offset. No lock is hold. If it just works one block later, than that is just the case.
void	setLevel (const d level, bool dB=true)
	Set the level of the signal generator.
void	reset (const d newFs)
	Reset the signal generator. Should be called whenever the output is based on a different sampling frequency. Note that derived classes from this class should call the base class!
vd	genSignal (const us nframes)
	Called whenever the implementation needs to create new samples.
