具有兩個調製器的Webaudio FM Synthesis合成

Question

F是載體，並且E和D是調製劑。

簡單的FM合成只有一個調製器，是webaudio非常簡單。

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();

但現在我想作這樣的事情。

兩個調製器即是。這在webaudio中如何實現？

Answer 1

迴應： 您需要連接到解除頻率而不是頻率。

例子： 嘿，我有你在我的網站的例子： http://gtube.de/

轉到發佈區的頭部，並選擇FM合成器。

在那裏你可以看到連接，你可以試試它（使用鍵盤A-L）！ :-)
