Detailed Description

template<typename SampleType = float>
class pulp::signal::ArT< SampleType >

Attack-Release, gate-driven.

Attack while the gate is high, sustain at 1, release when it falls.

USE: the sustained-gate workhorse — pad and drone VCAs, gate-CV amplitude, and sidechain duck-and-recover shapes (invert it through an AttenuverterT). When a sound has no decay stage, this is the right primitive; an ADSR with sustain pinned to 1 is the same shape with three more parameters to explain and get wrong.

active()

template<typename SampleType = float>

bool pulp::signal::ArT< SampleType >::active ( ) const

inline

current()

template<typename SampleType = float>

SampleType pulp::signal::ArT< SampleType >::current ( ) const

inline

gate()

template<typename SampleType = float>

void pulp::signal::ArT< SampleType >::gate ( bool on )

inline

Gate edges drive the envelope; repeated calls with the same state are no-ops, so this can be called every sample from a gate signal.

gate_off()

template<typename SampleType = float>

void pulp::signal::ArT< SampleType >::gate_off ( )

inline

gate_on()

template<typename SampleType = float>

void pulp::signal::ArT< SampleType >::gate_on ( )

inline

Convenience spelling with exactly the same level-before-advance sample ordering as gate(true).

next()

template<typename SampleType = float>

SampleType pulp::signal::ArT< SampleType >::next ( )

inline

prepare()

template<typename SampleType = float>

void pulp::signal::ArT< SampleType >::prepare ( double sample_rate )

inline

reset()

template<typename SampleType = float>

void pulp::signal::ArT< SampleType >::reset ( )

inline

set_attack_curve()

template<typename SampleType = float>

void pulp::signal::ArT< SampleType >::set_attack_curve ( float c )

inline

set_attack_ms()

template<typename SampleType = float>

void pulp::signal::ArT< SampleType >::set_attack_ms ( double ms )

inline

set_curve()

template<typename SampleType = float>

void pulp::signal::ArT< SampleType >::set_curve ( double c )

inline

Round-2 compatibility curve: 0 is linear and 1 is the strongest capacitor-like attack/release pair.

The shared engine's signed curves use opposite signs for rising and falling segments.

set_release_curve()

template<typename SampleType = float>

void pulp::signal::ArT< SampleType >::set_release_curve ( float c )

inline

set_release_ms()

template<typename SampleType = float>

void pulp::signal::ArT< SampleType >::set_release_ms ( double ms )

inline

stage()

template<typename SampleType = float>

EnvelopeStage pulp::signal::ArT< SampleType >::stage ( ) const

inline

value()

template<typename SampleType = float>

SampleType pulp::signal::ArT< SampleType >::value ( ) const

inline
