Periodic Class Reference

Base class for all periodic signals (that are exactly periodic based on the sampling frequency). Note that the sine wave generator is not exactly periodic as the frequency can be any floating point value. More...

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.
