    s.background(0);

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

      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);
