Detailed Description

A constant-tempo sub-segment of an automation curve.

Because the tempo is constant within each segment, the sample-space ratio equals the tick-space ratio, so the audio thread can evaluate the curve without accessing the tempo map.

◆ curve_algo

dsp::CurveOptions::Algorithm zrythm::dsp::AutomationTimelineDataCache::CachedAutomationSegment::curve_algo

Curve parameters from the automation point that drives this segment.

Definition at line 290 of file timeline_data_cache.h.

◆ curve_curviness

float zrythm::dsp::AutomationTimelineDataCache::CachedAutomationSegment::curve_curviness

Definition at line 291 of file timeline_data_cache.h.

◆ end_sample

units::sample_t zrythm::dsp::AutomationTimelineDataCache::CachedAutomationSegment::end_sample

Definition at line 273 of file timeline_data_cache.h.

◆ point_a_value

float zrythm::dsp::AutomationTimelineDataCache::CachedAutomationSegment::point_a_value

Values of the two automation points bracketing this segment.

Definition at line 286 of file timeline_data_cache.h.

◆ point_b_value

float zrythm::dsp::AutomationTimelineDataCache::CachedAutomationSegment::point_b_value

Definition at line 287 of file timeline_data_cache.h.

◆ ratio_end

float zrythm::dsp::AutomationTimelineDataCache::CachedAutomationSegment::ratio_end

Definition at line 283 of file timeline_data_cache.h.

◆ ratio_start

float zrythm::dsp::AutomationTimelineDataCache::CachedAutomationSegment::ratio_start

Position within the full automation point pair (0 = first point, 1 = second point).

For sub-segments split by tempo changes, these span a sub-range of [0, 1]. For flat hold segments, both are 1.0.

Definition at line 282 of file timeline_data_cache.h.

◆ start_sample

units::sample_t zrythm::dsp::AutomationTimelineDataCache::CachedAutomationSegment::start_sample

Absolute sample positions (for binary search).
