title: JavaScript Convert Blob to Float32Array (or other Typed Arrays)
body: <p>How do you convert a blob that was received with a WebSocket Binary message to a Float32Array (or other Typed Arrays : Uint32, Uint16, etc).</p>
  
  <p>I've tried to use the FileReader but the 'result' takes WAY too long to become available.  The result MUST be available on the next received WebSocket message.</p>
  
  <p>If I could get the WebSocket to receive an ArrayBuffer instead of a Blob, that would work.  How can I do that?</p>
