DSWaveformImage

DSWaveformImage - iOS, macOS & visionOS realtime audio waveform rendering

DSWaveformImage offers a native interfaces for drawing the envelope waveform of audio data in iOS, iPadOS, macOS, visionOS or via Catalyst. To do so, you can use

• WaveformImageView (UIKit) / WaveformView (SwiftUI) to render a static waveform from an audio file or
• WaveformLiveView (UIKit) / WaveformLiveCanvas (SwiftUI) to realtime render a waveform of live audio data (e.g. from AVAudioRecorder)
• WaveformImageDrawer to generate a waveform UIImage from an audio file

Additionally, you can get a waveform's (normalized) [Float] samples directly as well by creating an instance of WaveformAnalyzer.

Example UI (included in repository)

For a practical real-world example usage of a SwiftUI live audio recording waveform rendering, see RecordingIndicatorView.
