Classes
class	pulp::signal::SampleRateReducerT< SampleType >
	Sample-and-hold rate reducer with clock jitter and a reconstruction filter. More...
class	pulp::signal::LofiChainT< SampleType >
	The three lo-fi stages in the order the hardware they model applies them: quantise the word, hold it at a lower clock, then push it through an output stage that cannot represent the smallest codes. More...

Typedefs
using	pulp::signal::SampleRateReducer = SampleRateReducerT<float>
using	pulp::signal::SampleRateReducer64 = SampleRateReducerT<double>
using	pulp::signal::LofiChain = LofiChainT<float>
using	pulp::signal::LofiChain64 = LofiChainT<double>

Enumerations
enum class	pulp::signal::FloorCurve { pulp::signal::linear , pulp::signal::smoothstep }
	The curve applied above a floor threshold by floor_shape. More...

Functions
double	pulp::signal::quantize_bits (double x, double bits)
	Quantises to bits of resolution, mid-tread, symmetric about zero.
double	pulp::signal::dead_zone_saturate (double x, double dead_zone)
	A dead-zone saturator: a hard gap around zero, then a soft-limited slope.
template<typename Sample = double>
Sample	pulp::signal::floor_shape (Sample x, std::type_identity_t< Sample > threshold, FloorCurve curve)
	A noise-floor shaper: silence below threshold, rescaled above it.
