请问wavesurfer.js双声道波状图如何实现

initWavesurfer(){//初始化插件
                const _this = this
                this.wavesurfer = WaveSurfer.create({
                    container: '#waveform',
                    waveColor: '#39AB84',
                    progressColor: '#FF8C00',
                    split: false,
                    minPxPerSec: 8,
                    height: 100,
                    barWidth: 1,  
                    // barHeight: 1.5,
                    barHeight: 0.6,
                    hideScrollbar:true,
                    audioRate: '1',
                    abnormalvolume:{"1":"violet"},
                    emotionColor:{"1":"red"},
                    speedColor:{"1":"#955539"},
                    markdata:_this.markdata,
                    fs_rsxmldata:_this.fs_rsxmldata,
                    plugins: [
                        CursorPlugin.create({
                            showTime: true,
                            opacity: 0.2,
                            customShowTimeStyle: {
                                'background-color': '#000',
                                color: '#fff',
                                padding: '2px',
                                'font-size': '20px'
                            },
                        }),
                        // Timeline.create({
                        //   container: '#wave-timeline'
                        // }),
                        Regions.create()
                    ],
                })

这是部分代码，配置这块东西，求教学如何实现双声道波状图，现在实现的是单声道波状图

代码是否正确
