set_time_ms()

void sbl::dsp::primitives::CriticalDamp::set_time_ms ( float  ms, float  rate_hz  )

inline

Set settling time in milliseconds.

Note

All public methods are ISR-safe — bounded computation, no I/O.

Parameters

ms	Time for 95% settling (0 = instant)
rate_hz	Update rate in Hz (e.g., 1000 for block-rate, 48000 for audio-rate)

Computes the per-pole coefficient for a two-stage cascade. The combined system reaches 95% of a step change in ms milliseconds.

set_coefficient()

void sbl::dsp::primitives::CriticalDamp::set_coefficient ( float  a )

inline

Set coefficient directly (advanced use)

Parameters

a	Per-pole coefficient [0, 1]

process() [1/2]

float sbl::dsp::primitives::CriticalDamp::process ( float  target )

inline

Process one sample toward target.

Parameters

target

process() [2/2]

void sbl::dsp::primitives::CriticalDamp::process ( float *  buf, uint16_t  frames, float  target  )

inline

Fill buffer with smoothed trajectory toward target.

Parameters

buf	Output buffer (filled with per-sample smoothed values)
frames	Number of samples
target	Target value

Useful for generating per-sample coefficient ramps inside filter widgets.
