## Requirements



- iOS 8.0+

- macOS 10.10+

- Xcode 8.0+



## Installation:



### Manually



#### First

Check SonogramView.swift or MacSonogramView.swift and copy it to your project, then take a look on example for iOS or macOS, it's pretty straightforward, and don't forget to make sure, that you have your audiofile added to project/downloaded.



#### Second

You whould init anywhere the SonogramView() as nib or fram - doesnt matter.. 

```swift

let sView: SonogramView = SonogramView()

```

Provide your fileURL like: 

```swift

sView.addDurationOfFileWith(url: fileUrl!)

```

And just invoke the magic!

```swift

sView.convertToPoints()

```



# Playground:

Try it in Playground! :)



```Swift

import PlaygroundSupport



var fileUrl: URL?

do {

    fileUrl = PlaygroundSupport.playgroundSharedDataDirectory.appendingPathComponent("test.m4a")

    // User/Documents/Shared Playground Data

} catch {

    print(error)

}



var waveView: SonogramView = SonogramView()

waveView.addDurationOfFileWith(url: fileUrl!)

waveView.convertToPoints()

// And you are done!



// Customization of view

waveView.backgroundColor = .clear

let view = UIView(frame: CGRect(x: 0, y: 0, width: 300, height: 200))

view.backgroundColor = .white

view.addSubview(waveView)



waveView.frame.size.width = view.frame.width

waveView.frame.size.height = view.frame.height

waveView.center = view.center



PlaygroundPage.current.liveView = view // Showing in liveView with xCode Playground

```
