Recording and analyzing sound

Hi @Gordon,

Based on the code below:

var clipSeconds = 3, currentSecond = 0;
var w = new Waveform(512,{doubleBuffer:true,bits:16});
var a = new Uint16Array(512 * clipSeconds);
w.on("buffer", function(buf) {

  a.set(buf, currentSecond * 512);
  currentSecond++;

  if (currentSecond >= clipSeconds) {
    w.stop();

    E.FFT(a);
    var m=0,n=-1;
    for (var i=150;i<250;i++)if(a[i]>n)n=a[m=i];
    console.log(m.toFixed(0)+"Hz @ "+n);
  }
});
w.startInput(D2,512,{repeat:true});

My understanding is that all the sound as buffer will be stored in "a" from where once all the data is aggregated we could define the frequency.

When this code is deployed the flow hangs on "E.FFT(a);" and I cannot connect to the Puck anymore. Please advice.

Thank you.
