Recording and analyzing sound

Hi @Gordon,
1) You mean this code can still measure 500Hz with lower accuracy ?

var w = new Waveform(512,{doubleBuffer:true,bits:16}­);
var a = new Uint16Array(512);
w.on("buffer", function(buf) {
  a.set(buf);
  E.FFT(a);
  var m=0,n=-1;
  for (var i=100;i<500;i++)if(a[i]>n)n=a[m=i];
  console.log(m.toFixed(0)+"Hz @ "+n);
});
w.startInput(D2,512,{repeat:true});

2) Is it possible to use 1024 buffer size on behalf of other functionalities ?
