带有两个调制器的Webaudio FM Synthesis

Question

F是载体，E和D是调制器。

使用仅一个调制器进行简单的FM合成，在webaudio中非常简单。

var ctx = new AudioContext || webkitAudioContext();
var out = ctx.destination;

// Instantiating
var E = ctx.createOscillator(); // Modulator
var F = ctx.createOscillator(); // Carrier

// Setting frequencies
E.frequency.value = 440;
F.frequency.value = 440;

// Modulation depth
var E_gain = ctx.createGain();
E_gain.gain.value = 3000;

// Wiring everything up
E.connect(E_gain);
E_gain.connect(F.frequency);
F.connect(out);

// Start making sound
E.start();
F.start();

但现在我想做出类似的事情。

两个调制器即是。如何在webaudio中实现？

Answer 1

响应： 你需要连接到失谐而不是频率。

实施例： 嘿，我在我的网站上有一个例子给你： http://gtube.de/

转到头部的发布区域并选择FM合成器。

在那里你可以看到连接，你可以试一试（使用键盘A-L）！ ： - ）
