4.0.0 (21.06.2020)

• Fixed mediaelement-webaudio playback under Safari (#1964)
• Fixed the destroy method of the MediaElementWebAudio backend. Instead of destroying only the media element, the audio nodes are disconnected and the audio context is closed.

3.2.0 (24.10.2019)

• New MediaElementWebAudio backend (#1767):
  • Allows you to use Web Audio API with big audio files, loading audio like with MediaElement backend (HTML5 audio tag), so you can use the same methods of MediaElement backend for loading and playback. This way, the audio resource is not loaded entirely from server, but in ranges, allowing you to use WebAudio features, like filters, on audio files with a long duration. You can also supply peaks data, so the entire audio file does not have to be decoded. For example:

    wavesurfer.load(url | HTMLMediaElement, peaks, preload, duration);
    wavesurfer.play();
    wavesurfer.setFilter(customFilter);
