hark.bundle.js is broken

[roschler]

The bundle wrapper is doing something wrong. hark.bundle.js is broken. Take a look at the source and you immediately see that getMaxVolume() is not being called anywhere else in the source. I went back to the unbundled version and modernized the variable scope prefixes while I was at it, and it works now. Note: My version is formatted to be used as a module and I am importing wildemitted.js from a a sibling events directory, also as a module.

Here is my "unbundled" version. Tested and it works fine:

// Import dependencies (ensure WildEmitter is available as an ES6 module)

import WildEmitter from '../events/wildemitter.mjs';

export function getMaxVolume(analyser, fftBins) {
  let maxVolume = -Infinity;
  analyser.getFloatFrequencyData(fftBins);

  for (let i = 4, ii = fftBins.length; i < ii; i++) {
    if (fftBins[i] > maxVolume && fftBins[i] < 0) {
      maxVolume = fftBins[i];
    }
  }
  return maxVolume;
}

let audioContextType;
if (typeof window !== 'undefined') {
  audioContextType = window.AudioContext || window.webkitAudioContext;
}

let audioContext = null;

export function hark(stream, options) {
  let harker = new WildEmitter(); // Ensure WildEmitter is correctly imported or implemented

  if (!audioContextType) return harker;

  options = options || {};
  let smoothing = options.smoothing || 0.1,
    interval = options.interval || 50,
    threshold = options.threshold,
    play = options.play,
    history = options.history || 10;

  audioContext = options.audioContext || audioContext || new audioContextType();

  let analyser = audioContext.createAnalyser();
  analyser.fftSize = 512;
  analyser.smoothingTimeConstant = smoothing;
  let fftBins = new Float32Array(analyser.frequencyBinCount);

  let sourceNode;
  if (stream.jquery) stream = stream[0];
  if (stream instanceof HTMLAudioElement || stream instanceof HTMLVideoElement) {
    sourceNode = audioContext.createMediaElementSource(stream);
    if (typeof play === 'undefined') play = true;
    threshold = threshold || -50;
  } else {
    sourceNode = audioContext.createMediaStreamSource(stream);
    threshold = threshold || -50;
  }

  sourceNode.connect(analyser);
  if (play) analyser.connect(audioContext.destination);

  // Implement harker logic...

  return harker;
}
