Hi, everybody!

I’m trying to get the frequency information from audio stream from the microphone. I tried the following:

if (navigator.webkitGetUserMedia) {
   navigator.webkitGetUserMedia({ audio: true },
      function(stream) {
       alert(stream);
     context = new webkitAudioContext();
     analyser = context.createAnalyser();
         canvas = document.getElementById(‘analyser_render’);
     ctx = canvas.getContext(‘2d’);
     source = context.createMediaStreamSource(stream);
     source.connect(analyser); 
     frameLooper();
      },
      function(err) {
         console.log(“The following error occurred: ” + err.name);
      }
   );
} else {
   console.log(“getUserMedia not supported”);
}

Then I found out that the MediaStreamSource interface of Audio API is not supported yet. Are there any other ways to analyze audio from the mic?
