Use FFExtras to draw curves. Use https://github.com/phding/waveform-node to parse audio waves.

const extras = new FFExtras();

extras.init = function (InkPaint) {
  const graphic = new InkPaint.Graphics();
  this.container.addChild(graphic);
  this.graphic = graphic;
};

extras.update = function (time) {
  this.graphic.clear();
  this.graphic.lineStyle(2, 0xff0000);
  this.graphic.lineTo(...);
  ...
  this.graphic.closePath();
};
