Struct Lfo 

pub struct Lfo { /* private fields */ }

Low Frequency Oscillator for modulation effects.

Generates periodic control signals for tremolo, vibrato, phaser, etc. Uses a phase accumulator for efficient, RT-safe operation.

Implementations

impl Lfo

pub fn new(waveform: LfoWaveform, sample_rate: f64) -> Lfo

Create a new LFO with the given waveform and sample rate.

pub fn set_depth(&mut self, depth: f64)

Set modulation depth (0.0 = no modulation, 1.0 = full depth).

pub fn depth(&self) -> f64

Get the current depth.

pub fn set_waveform(&mut self, waveform: LfoWaveform)

Set the waveform shape.

pub fn waveform(&self) -> LfoWaveform

Get the current waveform.

pub fn tick_unipolar(&mut self) -> f64

Advance the LFO and return unipolar output (0.0 to depth).

Useful for tremolo depth where 0 = no cut, depth = full cut.

pub fn phase(&self) -> f64

Get current phase (0.0 - 1.0), useful for phase displays.

pub fn set_phase(&mut self, phase: f64)

Set phase directly (0.0 - 1.0), useful for sync.

Trait Implementations

impl Clone for Lfo

fn clone(&self) -> Lfo

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Lfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Modulator for Lfo

fn tick(&mut self) -> f64

Advance the LFO by one sample and return the output value.

Returns a value in the range [-depth, +depth]. For unipolar output (0 to depth), use tick_unipolar().

fn reset(&mut self)

Reset the modulator to its initial state.

fn set_rate(&mut self, hz: f64)

Set the modulation rate in Hz (for periodic modulators).

fn rate(&self) -> f64

Get current rate in Hz.

fn set_sample_rate(&mut self, sample_rate: f64)

Update sample rate when audio engine changes.
