# FDWaveformView
FDWaveformView is an easy way to display an audio waveform in your app. It is a nice visualization to show a playing audio file or to select a position in a file.
**:hatching_chick: Virtual tip jar: https://amazon.com/hz/wishlist/ls/EE78A23EEGQB**
Usage
-----
To use it, add an `FDWaveformView` using Interface Builder or programmatically and then just load your audio as per this example. Note: if your audio file does not have file extension, see this SO question.
```swift
let thisBundle = Bundle(for: type(of: self))
let url = thisBundle.url(forResource: "Submarine", withExtension: "aiff")
self.waveform.audioURL = url
```
Features
--------
**Set play progress** to highlight part of the waveform:
```swift
self.waveform.progressSamples = self.waveform.totalSamples / 2
```
**Zoom in** to show only part of the waveform, of course, zooming in will smoothly re-render to show progressively more detail:
```swift
self.waveform.zoomStartSamples = 0
self.waveform.zoomEndSamples = self.waveform.totalSamples / 4
```
**Enable gestures** for zooming in, panning around or scrubbing:
```swift
self.waveform.doesAllowScrubbing = true
self.waveform.doesAllowStretch = true
self.waveform.doesAllowScroll = true
```
**Supports animation** for changing properties:
```swift
UIView.animate(withDuration: 0.3) {
let randomNumber = arc4random() % self.waveform.totalSamples
self.waveform.progressSamples = randomNumber
}
```
Creates **antialiased waveforms** by drawing more pixels than are seen on screen. Also, if you resize me (autolayout) I will render more detail if necessary to avoid pixelation.
Supports **iOS12+** and Swift 5.
**Includes unit tests**, todo: run these on GitHub Actions
