What's new in this version

• BeatDetector analyzer class contributed by @alexdmiller (addresses #58)
• Implements #47. Caching of decoded SoundFile data (which used to block audio samples from being garbage collected) can now be disabled in two ways:
  • set the (new) third constructor argument to false: new SoundFile(this, filename, false)
  • method: soundfile.removeFromCache()
