Script Preparation code:

var ctx = new AudioContext();
var gain = ctx.createGain();
var oscillator = ctx.createOscillator();
var analyser = ctx.createAnalyser();

gain.gain.value = 0.01;
oscillator.frequency.value = 20;
oscillator.type = "square";
analyser.fftSize = 32768;

var fbuf = new Float32Array(analyser.frequencyBinCount);
var bbuf = new Uint8Array(analyser.frequencyBinCount);

oscillator.connect(analyser);
analyser.connect(gain);
gain.connect(ctx.destination);

oscillator.start();

Tests:

getFloatFrequencyData
analyser.getFloatFrequencyData(fbuf);
getByteFrequencyData
analyser.getByteFrequencyData(bbuf);
