set_coefficient()

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

inline

Set coefficient directly.

Note

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

a = 0.0 → hold previous output, 1.0 → instant (no smoothing).

Definition at line 33 of file parameter_smoother.hpp.

set_time_ms()

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

inline

Compute coefficient from settling time in milliseconds.

Sets coefficient so the smoother reaches ~95% of a step change in the given time at the given update rate.

Parameters

ms	Settling time in milliseconds (95% of step)
rate_hz	Update rate in Hz (e.g., 1000 for block-rate at 1kHz)

process()

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

inline

Process one sample toward target.

Parameters

target

The value to approach

Returns

Smoothed value

process_steps()

float sbl::dsp::primitives::ParameterSmoother::process_steps ( float  target, uint32_t  n  )

inline

Advance n steps toward target in one call.

Exactly equivalent to n consecutive process() calls. Lets a smoother whose coefficient was computed for a per-sample rate be advanced at block rate without stretching its settling time — pass the block size as n.

Parameters

target	The value to approach
n	Number of steps to advance

Returns

Smoothed value after n steps

value()

float sbl::dsp::primitives::ParameterSmoother::value ( ) const

inline

Current smoothed value.

coefficient()

float sbl::dsp::primitives::ParameterSmoother::coefficient ( ) const

inline

Current coefficient.

reset() [1/2]

void sbl::dsp::primitives::ParameterSmoother::reset ( )

inline

Reset to zero.

reset() [2/2]

void sbl::dsp::primitives::ParameterSmoother::reset ( float  initial )

inline

Reset to a specific value.
