Struct Smoother 

pub struct Smoother { /* private fields */ }

A parameter value smoother.

Can be used standalone for custom modulation, or integrated into FloatParameter via .with_smoother().

Thread Safety

Smoother is Send but not Sync - it requires &mut self for advancing state. This is intentional for audio thread usage.

Implementations

impl Smoother

pub fn new(style: SmoothingStyle) -> Self

Create a new smoother with the given style.

Sample rate must be set before use via set_sample_rate().

pub fn none() -> Self

Create a smoother with no smoothing (pass-through).

pub fn style(&self) -> SmoothingStyle

Get the smoothing style.

pub fn set_sample_rate(&mut self, sample_rate: f64)

Set the sample rate.

Call this from Processor::setup(). Recomputes coefficients based on time constants.

pub fn set_target(&mut self, target: f64)

Set a new target value.

Call this when the parameter value changes (typically at start of process block).

pub fn reset(&mut self, value: f64)

Reset immediately to a value (no smoothing).

Use when loading state or initializing to avoid ramps.

pub fn tick(&mut self) -> f64

Advance by one sample and return the smoothed value.

Call this once per sample in the audio loop.

pub fn current(&self) -> f64

Get current smoothed value without advancing.

pub fn target(&self) -> f64

Get the target value.

pub fn skip(&mut self, samples: usize)

Skip forward by n samples (for block processing).

This is equivalent to calling tick() n times but may be optimized for some smoothing styles.

pub fn fill(&mut self, buffer: &mut [f64])

Fill a slice with smoothed values (f64).

pub fn fill_f32(&mut self, buffer: &mut [f32])

Fill a slice with smoothed values (f32).

pub fn is_smoothing(&self) -> bool

Returns true if still smoothing toward target.

Trait Implementations
