title: WebAudio API sampling rate
body: <p>Is it possible to specify the sampling rate (<code>sampleRate</code> attribute of the <a href="https://dvcs.w3.org/hg/audio/raw-file/tip/webaudio/specification.html#AudioContext-section" rel="noreferrer"><code>AudioContext</code></a> object) for a real-time audio context?</p>
  
  <p>For what I read, it is possible to specify the <code>sampleRate</code> for an <a href="https://dvcs.w3.org/hg/audio/raw-file/tip/webaudio/specification.html#OfflineAudioContext-section" rel="noreferrer"><code>OfflineAudioContext</code></a> object (the constructor takes 3 arguments, the last one being the sample rate), but the real-time <code>AudioContext</code> doesn't take any arguments.</p>
  
  <p>I imagine is not possible, as probably that is defined by the browser itself, but maybe there's a way?</p>
