set_level_su()

void sbl::dsp::comp::Fader::set_level_su ( float  su )

inline

Port: set the fader level [0, 1]. Clamped, taper-mapped, and fed into internal smoother.

set_taper()

void sbl::dsp::comp::Fader::set_taper ( Taper  t )

inline

Parameter: set the taper curve (structural config). Recomputes target gain from current level.

process() [1/2]

void sbl::dsp::comp::Fader::process ( float *  buf, uint16_t  n  )

inline

Apply gain to a mono buffer in-place. Per-sample smoothing toward target gain — click-free.

Definition at line 62 of file fader.hpp.

process() [2/2]

void sbl::dsp::comp::Fader::process ( float *  buf_l, float *  buf_r, uint16_t  n  )

inline

Apply gain to stereo buffers in-place. Same smoothed gain applied to both channels per sample.

Definition at line 72 of file fader.hpp.

References sbl::dsp::primitives::ParameterSmoother::process().

tick()

float sbl::dsp::comp::Fader::tick ( uint16_t  n )

inline

Advance the smoother by n samples' worth without processing audio. Call once per block with the block size for control-rate gain updates (e.g., send levels) — settling time matches per-sample process() regardless of call rate. Returns the current smoothed gain.

gain()

float sbl::dsp::comp::Fader::gain ( ) const

inline

Current smoothed gain value (after taper mapping + smoothing).

Definition at line 92 of file fader.hpp.

level()

float sbl::dsp::comp::Fader::level ( ) const

inline

Raw su level (before taper mapping).

Definition at line 95 of file fader.hpp.

reset()

void sbl::dsp::comp::Fader::reset ( )

inline

Reset smoother state and level to defaults.

Definition at line 98 of file fader.hpp.
