let spectrum = fft.analyze();
if (spectrum.some((i) => i > 0)) {
const tensor = tf.tensor2d(spectrum, [64, 4]);
tensor.print();
}

for (var i = 0; i < spectrum.length; i++) {
var angle = s.map(i, 0, spectrum.length, 0, 360);
var amp = spectrum[i];
var r = s.map(amp, 0, 256, 20, 100);
//fill(i, 255, 255);
var x = r * s.cos(angle);
var y = r * s.sin(angle);
s.stroke(i, 255, 255);
s.line(0, 0, x, y);
//vertex(x, y);
//var y = map(amp, 0, 256, height, 0);
//rect(i * w, y, w - 2, height - y);
