+ * 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} hideCursor=false Whether to hide the mouse cursor
+ * when one would normally be shown by default.
+ * @property {boolean} ignoreSilenceMode=false If true, ignores device silence mode
+ * when using the `WebAudio` backend.
+ * @property {boolean} interact=true Whether the mouse interaction will be

+ * 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 {SplitChannelOptions} splitChannelsOptions={} Options for splitChannel rendering
+ * @property {boolean} vertical=false Render the waveform vertically instead of horizontally.
