ReadonlydurationThe realised duration, seconds (lengthSamples / sampleRate).
Readonlyf0Readonlyf1ReadonlyinverseThe inverse filter, normalised so stimulus ⊛ inverse peaks at 1 at sample lengthSamples − 1.
ReadonlyLThe sweep-rate constant T / ln(f1/f0), seconds — the time the frequency takes to grow by e.
Readonlylengthround(durationS · sampleRate) — the length of both stimulus and inverse.
ReadonlysampleReadonlystimulusThe exponential sine sweep, x(t), faded at both ends.
A generated sweep and its Farina inverse filter, with the constants a caller reads back.
