SimpleFmSynth

Struct SimpleFmSynth 

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

Простой FM синтезатор на основе двух операторов

Базовая FM архитектура: один модулятор модулирует один carrier. Идеально подходит для:

  • Создания металлических тембров
  • Эмуляции колокольчиков
  • Сложных гармонических структур

§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 FM синтезатор с соотношением частот 2:1
let mut fm = SimpleFmSynth::<f32>::new(
    440.0,  // частота несущей (A4)
    2.0,    // модулятор на октаву выше
    1.5     // индекс модуляции
);
fm.init(44100.0);

// Генерируем семпл
let mut output = [0.0_f32];
fm.process(None, &mut output, &ctx).unwrap();
let sample = output[0];
