Detailed Description

template<typename CurveEngine = FloatDefaultWarp>
class sbl::dsp::SegmentGenerator< CurveEngine >

Definition at line 46 of file segment.hpp.

Member Function Documentation

active()

template<typename CurveEngine = FloatDefaultWarp>

bool sbl::dsp::SegmentGenerator< CurveEngine >::active ( ) const

inline

Definition at line 130 of file segment.hpp.

References sbl::dsp::Complete, and sbl::dsp::Idle.

configure()

template<typename CurveEngine = FloatDefaultWarp>

void sbl::dsp::SegmentGenerator< CurveEngine >::configure ( const Segment *  segments, uint8_t  count, int8_t  sustain_index = -1  )

inline

Configure the segment sequence.

Parameters

segments	Array of segments (copied internally, up to MAX_SEGMENTS)
count	Number of segments
sustain_index	Segment index to hold at (-1 = no sustain)

Definition at line 58 of file segment.hpp.

References sbl::dsp::SegmentGenerator< CurveEngine >::MAX_SEGMENTS.

current_segment_index()

template<typename CurveEngine = FloatDefaultWarp>

uint8_t sbl::dsp::SegmentGenerator< CurveEngine >::current_segment_index ( ) const

inline

Definition at line 135 of file segment.hpp.

gate_off()

template<typename CurveEngine = FloatDefaultWarp>

void sbl::dsp::SegmentGenerator< CurveEngine >::gate_off ( )

inline

Release the envelope. If in sustain, jumps to the next segment (typically release). If running pre-sustain, jumps to release. If no sustain configured, does nothing.

Definition at line 83 of file segment.hpp.

References sbl::dsp::Running, and sbl::dsp::Sustain.

gate_on()

template<typename CurveEngine = FloatDefaultWarp>

void sbl::dsp::SegmentGenerator< CurveEngine >::gate_on ( )

inline

Start the envelope from segment 0. If already running, restarts from the current level (retrigger behavior).

Definition at line 73 of file segment.hpp.

References sbl::dsp::Idle, and sbl::dsp::Running.

level()

template<typename CurveEngine = FloatDefaultWarp>

float sbl::dsp::SegmentGenerator< CurveEngine >::level ( ) const

inline

Definition at line 128 of file segment.hpp.

process()

template<typename CurveEngine = FloatDefaultWarp>

void sbl::dsp::SegmentGenerator< CurveEngine >::process ( float *  out, uint16_t  frames  )

inline

Fill output buffer with envelope levels (float [0.0, 1.0]).

Definition at line 108 of file segment.hpp.

References sbl::dsp::Running, and sbl::dsp::Segment::target.

retrigger()

template<typename CurveEngine = FloatDefaultWarp>

void sbl::dsp::SegmentGenerator< CurveEngine >::retrigger ( )

inline

Retrigger: restart from current level without requiring gate_off first.

Definition at line 98 of file segment.hpp.

References sbl::dsp::Running.

set_sample_rate()

template<typename CurveEngine = FloatDefaultWarp>

void sbl::dsp::SegmentGenerator< CurveEngine >::set_sample_rate ( uint32_t  sr )

inline

Definition at line 67 of file segment.hpp.

state()

template<typename CurveEngine = FloatDefaultWarp>

SegmentState sbl::dsp::SegmentGenerator< CurveEngine >::state ( ) const

inline

Definition at line 134 of file segment.hpp.
