 1 | # IHEqualizerView
 2 | A simple, intuitive audio asset visualiser for iOS.
 3 | 
 4 | # Example
 5 | To run the example project, clone the repo, and run `pod install` from the Example directory first.
 6 | 
 7 | # Highlights
 8 | Very simple and lightweight. Color Coding for differnt output range. Written in Swift.
 9 | 
10 | * Pale red for low output
11 | * Light red for medium
12 | * Red for high output
13 | * Based on the output distribution pattern of Recorder App from Apple
14 | * Option to pre-render audio file
15 | 
16 | # Getting Started
17 | 
18 | To begin using IHEqualizerView you must first make sure you have the proper build requirements.
19 | 
20 | 
21 | # Screen Recordings

25 | 
26 | # Build Requirements
27 | 
28 | ## iOS
29 | 
30 | 10.0+
31 | 
32 | ## Installation
33 | 
34 | IHEqualizerView is available through [CocoaPods](http://cocoapods.org). To install
35 | it, simply add the following line to your Podfile:
36 | 
37 | ```ruby
38 | pod 'IHEqualizerView'
39 | ```
40 | 
41 | # Adding Manually To Project
42 | 
43 | You can add IHEqualizerView to your project in a few ways: 
44 | 
45 | The way to use IHEqualizerView is to download the IHWaveFormView class file in your project as is and use.
46 | 
47 | # Usage
48 | 
49 | ## StoryBoard
50 | 
51 | Make the UIView a subclass of IHEqualizerView, make its outlet and initialise as follows:
52 | 
53 |     @IBOutlet var musicView: IHWaveFormView!
54 |     extension ViewController: IHWaveFormViewDataSource {
55 |     
56 |     func urlToPlay() -> URL {
57 |         var url : URL?
58 |         let path = Bundle.main.path(forResource: "bensound-sunny.mp3", ofType:nil)!
59 |         url = URL(fileURLWithPath: path)
60 |         
61 |         return url!
62 |     }
63 | 
64 |     func lineWidth() -> CGFloat { 2 }
65 | 
66 |     func lineSeperation() -> CGFloat { 1 }
67 | 
68 |     func shouldPreRender() -> Bool { true }
69 |     }
