Description

A UIView subclass that displays waveform of a provided local audio file.

This view has 2 gesture recognizers attached:

1. UITapGestureRecognizer - Play - Pause associated with a view audio file.
2. UIPanGestureRecognizer - Seek audio file to specified position.

There are 3 public properties:

• normalColor - default color of waveform, fills section of waveform that is yet to be played.
• progressColor - already played section of waveform has this color.
• allowSpacing - inserts a little spacing between bars in waveform.

Usage

Example:

      let waveform = try ASWaveformPlayerView(audioURL: audioURL, // URL to local a audio file
                                              sampleCount: 1024, // higher numbers makes waveform more detailed
                                              amplificationFactor: 500) // constant that affects height of each 'bar' in waveform

      waveform.normalColor = .lightGray
      waveform.progressColor = .orange
      //with high sampleCount passed to init method to avoid artifacts set this to false
      waveform.allowSpacing = false
