Recording and analyzing sound

Hi @Gordon,

I updated my puck to 1v95.153 and uploaded this code:

function fq(sec){
  var cSec=0, sBuff=new Uint8Array(sec);
  var w=new Waveform(512,{doubleBuffer:true,bits:8})­;
  var a=new Uint16Array(512);
  w.on("buffer", function(buf) {
    a.set(buf);
    E.FFT(a);
    var m=0,n=-1;
    for (var i=150;i<250;i++)if(a[i]>n)n=a[m=i];
    sBuff[cSec]=m.toFixed(0);
    console.log(sBuff[cSec]+"Hz @ "+n);
    cSec++;
    if (cSec >= sec) {
      w.stop();
      var v=E.sum(sBuff)/sec;
      var rKey=new Date(Date.now()).toString();
      console.log(rKey,v);
    }
  });
  w.startInput(D2,512,{repeat:true});
}

which worked before.
When you call fq(3) for example, the puck got reset. The problem comes from E.FFT(a);

Thank you.
