JSWaveform provides native Swift and SwiftUI components. For now, it has 2 major SwiftUI views:
AudioPlayerViewAudioVisualizerView
AudioPlayerView renders audio player which consits of play/pause button, downsampled waveform and time pitch effect button.
let url = Bundle.main.url(forResource: "Example", withExtension: "aif")
AudioPlayerView(audioURL: url!)If you want to configure it, you can, by setting AudioPlayer.Configuration in it's init.
AudioVisualizerView renders audio visualizer which animates AudioVisualizerShape based on audio amplitudes. This image shows default animation called symetricMiddleHigh where peak amplitudes are in the middle and average on the sides. You can see more available animations and set them using AudioVisualizer.Configuration.
let url = Bundle.main.url(forResource: "Example", withExtension: "aif")
AudioVisualizerView(audioURL: url!)You can also play/stop audio. Example:
Toggle("Play audio", isOn: $playAudio)
.tint(.blue)
.onChange(of: playAudio) { _, _ in
if playAudio {
audioVisualizerView.playAudio()
}
else {
audioVisualizerView.stopAudio()
}
}If you want to configure it, you can, by setting AudioVisualizer.Configuration in its init.
