javascript - Multiple sources for AudioContext() - Stack Overflow

I have two one-second audio sources as follows:

var context = system.AudioContext();
var source = context.createBufferSource();

var audioBuffer1 = context.createBuffer(1, float32Array_1.length, context.sampleRate);
audioBuffer1.getChannelData(0).set(float32Array_1);

var audioBuffer2 = context.createBuffer(1, float32Array_2.length, context.sampleRate);
audioBuffer2.getChannelData(0).set(float32Array_2);

Now I want to play these two audio sources with no delay between them. For a single source I can play the audio with the following code:

source.buffer = audioBuffer1;
source.connect(context.destination);
source.start(0);

How can I attach the second source such that there would be no delay between them.

• Is the idea that you want to play them simultaneously, or that you want them to play sequentially ? – Kevin Ennis Commented Aug 11, 2014 at 15:48
• The idea is to play them sequentially with no glitch. – Belaviyo Commented Aug 11, 2014 at 19:04

var context = system.AudioContext();
var source = context.createBufferSource();
var source2 = context.createBufferSource();

var audioBuffer1 = context.createBuffer(1, float32Array_1.length, context.sampleRate);
audioBuffer1.getChannelData(0).set(float32Array_1);

var audioBuffer2 = context.createBuffer(1, float32Array_2.length, context.sampleRate);
audioBuffer2.getChannelData(0).set(float32Array_2);

source.buffer = audioBuffer1;
source.connect(context.destination);

source2.buffer = audioBuffer2;
source2.connect(context.destination);

var time = context.currentTime;

source.start(time);
source2.start(time+audioBuffer1.duration);
