配置信息

option	type	default	English description	translate
audioRate	float	1	Speed at which to play audio. Lower number is slower.	播放音频的速度。数值越低，速度越慢。
audioContext	object	none	Use your own previously initialized AudioContext or leave blank.	none
audioScriptProcessor	object	none	Use your own previously initialized ScriptProcessorNode or leave blank.	使用您自己先前初始化的ScriptProcessorNode或留空。
autoCenter	boolean	true	If a scrollbar is present, center the waveform around the progress.	如果出现滚动条，则将波形围绕进度居中。
backend	string	WebAudio	WebAudio, MediaElement or MediaElementWebAudio. MediaElement is a fallback for unsupported browsers.	WebAudio, MediaElement或MediaElementwebAudio。MediaElement是不受支持的浏览器的备用方案。
backgroundColor	string	none	Change background color of the waveform container.	改变波形容器的背景颜色。
barGap	number	none	The optional spacing between bars of the wave, if not provided will be calculated in legacy format.	波条之间的可选间距，如果没有提供，将以遗留格式计算。
barHeight	number	1	Height of the waveform bars. Higher number than 1 will increase the waveform bar heights.	波形条的高度。大于1的数字将增加波形条的高度。
barMinHeight	number	null	Minimum height to draw a waveform bar. Default behavior is to not draw a bar during silence.	绘制波形条的最小高度。默认行为是在静默期间不画条。
barRadius	number	0	The radius that makes bars rounded.	使bars变圆的半径
barWidth	number	none	If specified, the waveform will be drawn like this: ▁ ▂ ▇ ▃ ▅ ▂	如果指定，波形将像这样绘制▁ ▂ ▇ ▃ ▅ ▂
closeAudioContext	boolean	false	Close and nullify all audio contexts when the destroy method is called.	当destroy方法被调用时，关闭并使所有音频上下文无效。
container	mixed	none	CSS-selector or HTML-element where the waveform should be drawn. This is the only required parameter.	css选择器或html元素，其中应该绘制波形。这是惟一必需的参数。
cursorColor	string	#333	The fill color of the cursor indicating the playhead position.	指针的填充颜色，表示播放头位置。
cursorWidth	integer	1	Measured in pixels.	以像素为单位
drawingContextAttributes	object	{desynchronized: true}	Specify canvas 2d drawing context attributes.	指定画布2d绘图上下文属性。
fillParent	boolean	true	Whether to fill the entire container or draw only according to minPxPerSec.	是否填充整个容器或仅根据minPxPerSec绘制。
forceDecode	boolean	false	Force decoding of audio using web audio when zooming to get a more detailed waveform.	在缩放时使用web音频强制解码音频以获得更详细的波形。
height	integer	128	The height of the waveform. Measured in pixels.	波形的高度。以像素为单位。
