	//	5. Avoid exposing implementation details on user objects (eg. expando properties)

	// declare themselves as anonymous modules, and avoid setting a global if an

 * @typedef {Object} WavesurferParams
 * @property {AudioContext} audioContext=null Use your own previously

 * @property {number} audioRate=1 Speed at which to play audio. Lower number is
 * slower.
 * @property {ScriptProcessorNode} audioScriptProcessor=null Use your own previously
 * initialized ScriptProcessorNode or leave blank.
 * @property {boolean} autoCenter=true If a scrollbar is present, center the
 * waveform on current progress
 * @property {number} autoCenterRate=5 If autoCenter is active, rate at which the
 * waveform is centered
 * @property {boolean} autoCenterImmediately=false If autoCenter is active, immediately
 * center waveform on current progress
 * @property {string} backend='WebAudio' `'WebAudio'|'MediaElement'|'MediaElementWebAudio'` In most cases
 * you don't have to set this manually. MediaElement is a fallback for unsupported browsers.
 * MediaElementWebAudio allows to use WebAudio API also with big audio files, loading audio like with
 * MediaElement backend (HTML5 audio tag). You have to use the same methods of MediaElement backend for loading and
 * playback, giving also peaks, so the audio data are not decoded. In this way you can use WebAudio features, like filters,
 * also with audio with big duration. For example:
 * ` wavesurfer.load(url | HTMLMediaElement, peaks, preload, duration);
 *   wavesurfer.play();
 *   wavesurfer.setFilter(customFilter);
 * `
 * @property {string} backgroundColor=null Change background color of the
 * waveform container.
 * @property {number} barHeight=1 The height of the wave bars.
 * @property {number} barRadius=0 The radius of the wave bars. Makes bars rounded
 * @property {number} barGap=null The optional spacing between bars of the wave,
 * if not provided will be calculated in legacy format.
 * @property {number} barWidth=null Draw the waveform using bars.
 * @property {number} barMinHeight=null If specified, draw at least a bar of this height,
 * eliminating waveform gaps
 * @property {boolean} closeAudioContext=false Close and nullify all audio
 * contexts when the destroy method is called.
 * @property {!string|HTMLElement} container CSS selector or HTML element where
 * the waveform should be drawn. This is the only required parameter.
 * @property {string} cursorColor='#333' The fill color of the cursor indicating
 * the playhead position.
 * @property {number} cursorWidth=1 Measured in pixels.
 * @property {object} drawingContextAttributes={desynchronized: false} Drawing context
 * attributes.
 * @property {number} duration=null Optional audio length so pre-rendered peaks
 * can be display immediately for example.
 * @property {boolean} fillParent=true Whether to fill the entire container or
 * draw only according to `minPxPerSec`.
 * @property {boolean} forceDecode=false Force decoding of audio using web audio
 * when zooming to get a more detailed waveform.
 * @property {number} height=128 The height of the waveform. Measured in
 * pixels.
 * @property {boolean} hideScrollbar=false Whether to hide the horizontal
 * scrollbar when one would normally be shown.
 * @property {boolean} interact=true Whether the mouse interaction will be
 * enabled at initialization. You can switch this parameter at any time later
 * on.
 * @property {boolean} loopSelection=true (Use with regions plugin) Enable
 * looping of selected regions
 * @property {number} maxCanvasWidth=4000 Maximum width of a single canvas in
 * pixels, excluding a small overlap (2 * `pixelRatio`, rounded up to the next
 * even integer). If the waveform is longer than this value, additional canvases
 * will be used to render the waveform, which is useful for very large waveforms
 * that may be too wide for browsers to draw on a single canvas.
 * @property {boolean} mediaControls=false (Use with backend `MediaElement` or `MediaElementWebAudio`)
 * this enables the native controls for the media element
 * @property {string} mediaType='audio' (Use with backend `MediaElement` or `MediaElementWebAudio`)
 * `'audio'|'video'` ('video' only for `MediaElement`)
 * @property {number} minPxPerSec=20 Minimum number of pixels per second of
 * audio.
 * @property {boolean} normalize=false If true, normalize by the maximum peak
 * instead of 1.0.
 * @property {boolean} partialRender=false Use the PeakCache to improve
 * rendering speed of large waveforms
 * @property {number} pixelRatio=window.devicePixelRatio The pixel ratio used to
 * calculate display
 * @property {PluginDefinition[]} plugins=[] An array of plugin definitions to
 * register during instantiation, they will be directly initialised unless they
 * are added with the `deferInit` property set to true.
 * @property {string} progressColor='#555' The fill color of the part of the
 * waveform behind the cursor. When `progressColor` and `waveColor` are the same
 * the progress wave is not rendered at all.
 * @property {boolean} removeMediaElementOnDestroy=true Set to false to keep the
 * media element in the DOM when the player is destroyed. This is useful when
 * reusing an existing media element via the `loadMediaElement` method.
 * @property {Object} renderer=MultiCanvas Can be used to inject a custom
 * renderer.
 * @property {boolean|number} responsive=false If set to `true` resize the
 * waveform, when the window is resized. This is debounced with a `100ms`
 * timeout by default. If this parameter is a number it represents that timeout.
 * @property {boolean} rtl=false If set to `true`, renders waveform from
 * right-to-left.
 * @property {boolean} scrollParent=false Whether to scroll the container with a
 * lengthy waveform. Otherwise the waveform is shrunk to the container width
 * (see fillParent).
 * @property {number} skipLength=2 Number of seconds to skip with the
 * skipForward() and skipBackward() methods.
 * @property {boolean} splitChannels=false Render with separate waveforms for
 * the channels of the audio
 * @property {string} waveColor='#999' The fill color of the waveform after the
 * cursor.
 * @property {object} xhr={} XHR options. For example:
 * `let xhr = {
 *     cache: 'default',
 *     mode: 'cors',
 *     method: 'GET',
