Audio visualisation of song
- iOS 8.0+
- macOS 10.10+
- Xcode 8.0+
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.
You whould init anywhere the SonogramView() as nib or fram - doesnt matter..
let sView: SonogramView = SonogramView()
Provide your fileURL like:
sView.addDurationOfFileWith(url: fileUrl!)
And just invoke the magic!
sView.convertToPoints()
Try it in Playground! :)
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
