LFO

Struct LFO 

Source
pub struct LFO<T: Transcendental> { /* private fields */ }
Expand description

LFO генератор (Low Frequency Oscillator)

Генерирует низкочастотные сигналы для модуляции параметров. Частотный диапазон: 0.01 Hz - 100 Hz.

§Режимы работы

  • Биполярный: выходной сигнал в диапазоне [-1, 1]
  • Униполярный: выходной сигнал в диапазоне [0, 1]

§Пример

use rill_core::time::ClockTick;
use rill_core::traits::ActionContext;
use rill_core_dsp::generators::*;
use rill_core_dsp::Algorithm;

let tick = ClockTick::default();
let ctx = ActionContext::new(&tick);

// Создаём LFO для модуляции частоты фильтра
let mut lfo = LFO::<f32>::new(
    5.0,              // 5 Hz
    Waveform::Sine,
    true              // биполярный режим (-1..1)
);
lfo.init(44100.0);

// Генерируем модуляционный сигнал
let mut output = [0.0_f32];
lfo.process(None, &mut output, &ctx).unwrap();
let modulation = output[0];

Implementations§

impl<T: Transcendental> LFO<T>

Source

pub fn new(frequency: f32, waveform: Waveform, bipolar: bool) -> Self

Создать новый LFO

§Arguments
  • frequency - частота в Hz (0.01 - 100)
  • waveform - форма волны
  • bipolar - true для биполярного режима (-1..1), false для униполярного (0..1)
Source

pub fn with_phase_offset(self, offset: T) -> Self

Создать LFO с фазовым смещением

Source

pub fn set_bipolar(&mut self, bipolar: bool)
