如何快速更改声波

Question

I found how to create Sound wave From FDWaveformView Pods , but I can't modify to create a this type of wave screenshot below:

Here is what I am trying to do:

The screenshot is taken from Iphone:

This code creates sine wave but I need to create pulse waves:

    soundWaveView.delegate = self
    soundWaveView.alpha = 0.0
    soundWaveView.audioURL = mainTrackURL
    soundWaveView.zoomSamples = 0 ..< soundWaveView.totalSamples / 3
    soundWaveView.doesAllowScrubbing = false
    soundWaveView.doesAllowStretch = false
    soundWaveView.doesAllowScroll = false
    soundWaveView.wavesColor = UIColor(red: 46/255, green: 188/255, blue: 191/255, alpha: 1)
    soundWaveView.progressColor = UIColor(red: 251/255, green: 237/255, blue: 101/255, alpha: 1)
    do {
        try AVAudioSession.sharedInstance().setActive(true)
        playerSoundWave = try AVAudioPlayer(contentsOf: mainTrackURL!, fileTypeHint: AVFileType.mp4.rawValue)
        songTotalTime = Double((playerSoundWave?.duration)!)
    }
    catch let error {
        print(error.localizedDescription)
    }
