I'm new to the iOS game, and I'm trying to use AudioKit to plot a output waveform graph. My input is the microphone. I was able to get a signal from the mic, but I'm not able to figure out how to set up a graph view, or how to access their plot data even.
This playground: http://audiokit.io/playgrounds/Output%20Waveform%20Plot/
Shows how to plot using liveView
in the playground, but not how to convert that to a UIView. The only code I have is from that playground example.
Is there a way to turn a CGRect
into a plotted real-time graph?
Any help would be appreciated! Even just pointing me in the right direction.

This is from the audio kit example code. If you put this into your view's class, it should work. This is what has worked for me.
var mic: AKMicrophone!
var tracker: AKFrequencyTracker!
var silence: AKBooster!
@IBOutlet weak var audioInputPlot: EZAudioPlot!
override func viewDidLoad() {
super.viewDidLoad()
AKSettings.audioInputEnabled = true
mic = AKMicrophone()
tracker = AKFrequencyTracker(mic)
silence = AKBooster(tracker, gain: 0)
setupPlot()
}
func setupPlot() {
let plot = AKNodeOutputPlot(mic, frame: audioInputPlot.bounds)
plot.plotType = .rolling
plot.shouldFill = true
plot.shouldMirror = true
plot.color = UIColor.blue
audioInputPlot.addSubview(plot)
}
