如何快速更改聲波

Question

我發現了如何從FDWaveformView Pods創建聲波，但是我無法修改以在下面創建這種類型的聲波屏幕截圖：

這是我正在嘗試做的事情：

屏幕截圖來自Iphone：

這段代碼創建了正弦波，但是我需要創建脈沖波：

    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)
    }

問題：如何修改或創建聲波？

有人可以向我解釋如何創建和修改聲波，我已經嘗試修改但沒有結果。 任何幫助將不勝感激。

提前致謝。
