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. To use it, add an FDWaveformView using Interface Builder or programmatically and then just load your audio as per this example.

Features

  • Set play progress to highlight part of the waveform
  • Zoom in to show only part of the waveform, of course, zooming in will smoothly re-render to show progressively more detail
  • Enable gestures for zooming in, panning around or scrubbing
  • Supports animation for changing properties
  • Creates antialiased waveforms by drawing more pixels than are seen on screen
  • Supports iOS8+ and Swift 3
  • Includes unit tests which run successfully using Travis CI
