I am using a SoundCloud URL as audio.src . It is only playing the unprocessed version when i run it through the delay chain i have.
Here is the fiddle:
http://jsfiddle.net/ehsanziya/nwaH3/
var context = new webkitAudioContext();
var audio = new Audio(); //creates a HTML5 Audio Element
url = 'http://api.soundcloud.com/tracks/33925813/stream' + '?client_id=c625af85886c1a833e8fe3d740af753c';
//wraps the soundcloud stream to an audio element.
audio.src = url;
var source = context.createMediaElementSource(audio);
var input = context.createGainNode();
var output = context.createGainNode();
var fb = context.createGainNode();
fb.gain.value = 0.4;
var delay = context.createDelayNode();
delay.delayTime.value = 0.5;
//dry
source.connect(input);
input.connect(output);
//wet
input.connect(delay);
delay.connect(fb);
fb.connect(delay);
delay.connect(output);
source.mediaElement.play();
The chain works with Oscillator node.
What is the reason for it?
And is there any other way of processing a streaming sound from SoundCloud with Web Audio API?
