从soundcloud设置web audio api源节点 [英] Setup web audio api source node from soundcloud

问题描述

我想知道是否有任何方法可以创建源节点（ https://dvcs.w3.org/hg/audio/raw-file/tip/webaudio/specification.html#MediaElementAudioSourceNode 。

I would like to know if there is any way to create a source node ( https://dvcs.w3.org/hg/audio/raw-file/tip/webaudio/specification.html#MediaElementAudioSourceNode) from a soundcloud track.

我对网络音频API很满意，但对于soundcloud sdk是新手，据我所知，它依赖于soundmanager2。那么也许有一些来自soundmanager2的选项？

I'm ok with the web audio API, but new to the soundcloud sdk, as far I understand it relies on soundmanager2. So maybe there is some options from soundmanager2 available?

推荐答案

您可以请求一个曲目，然后使用 stream_url 属性，您可以为音频元素设置为 src ，用作MediaSourceNode。

You can request a track and then use stream_url property, that you can set as src for the audio element, to be used as MediaSourceNode.

这是一个示例代码：

var context = new webkitAudioContext(),
    audio = new Audio(),
    source,
    // `stream_url` you'd get from 
    // requesting http://api.soundcloud.com/tracks/6981096.json
    url = 'http://api.soundcloud.com/tracks/6981096/stream' +
          '?client_id=YOUR_CLIENT_ID';

audio.src = url;
source = context.createMediaElementSource(audio);
source.connect(context.destination);
source.mediaElement.play();
