pole_radius_from_decay()

MAYAFLUX_API double MayaFlux::Kinesis::Discrete::pole_radius_from_decay ( double  seconds, double  sample_rate  )

noexcept

Pole radius whose impulse response falls by 1/e in a given time.

Parameters

seconds	Ring time, floored at one sample
sample_rate	Sample rate in Hz

Returns

decay_per_sample, floored at one sample and held just below the unit circle

There is no upper limit on the ring time other than the radius staying strictly inside the unit circle.
