Properties

Name	Type	Description
`kind`readonly	`TimeCurveKind`
`durationSec`readonly	`number`	Length of the segment on the clip's own clock, seconds.
`amount`readonly	`number`	How much of the segment the effect claims, 0–1. More `hold`: the fraction frozen. `ramp`: the depth of the rate swing. `stutter`: the frozen fraction of each step. `reverse`: the fraction run backwards. Zero makes every kind behave as `linear`, which is the honest neutral rather than a special case to branch on.
`stepSec`readonly	`number`	`stutter` only: one freeze-and-catch-up cycle, seconds.
`reversibleSec`readonly	`number`	`reverse` only: how far back the caller can actually go, in source seconds. More Running a re-simulated stream backwards is impossible without keeping the states to go back to, so the reversible window is a property of the consumer's buffer and has to be supplied rather than assumed. A curve never returns an offset below `-reversibleSec`; a consumer with no buffer passes zero and gets no reversal at all.
