            }
            .padding()
        }
    }

    @ViewBuilder
    func drawerSection<D: WaveformDrawing>(
        title: String,
        drawer: D
    ) -> some View {
        VStack(alignment: .leading, spacing: 8) {
            Text(title)
                .font(.headline)

            WaveformScrubber(
                drawer: drawer,

### WaveformScrubber Callbacks for Events

Source: https://github.com/lkora/waveformscrubber/blob/main/README.md

Implement callbacks to react to waveform events such as metadata loading and user scrubbing gestures. `onInfoLoaded` provides audio metadata, and `onGestureActive` indicates when the user is interacting with the scrubber.

```swift
WaveformScrubber(
    drawer: BarDrawer(),
    url: audioURL,
    progress: $progress,
    onInfoLoaded: { audioInfo in
        // Fired once the audio file's metadata is available.
        print("Audio duration: \(audioInfo.duration)")
    },
    onGestureActive: { isDragging in
        // Fired when the user starts or stops dragging the waveform.
        if isDragging {
            print("User is scrubbing.")
        } else {
            print("User finished scrubbing.")
        }
    }
)
```

--------------------------------

```swift
import SwiftUI
import WaveformScrubber

struct BasicExampleView: View {
    // URL to your audio file
    private let audioURL = Bundle.main.url(forResource: "example", withExtension: "mp3")!

    @State private var progress: CGFloat = 0.25

    var body: some View {
        VStack {
            Text("Playback Progress: \(Int(progress * 100))%")
            
            WaveformScrubber(
                drawer: BarDrawer(), // The default bar-style drawer
                url: audioURL,
                progress: $progress
            )
            .frame(height: 100)
            .padding()
            
            // Control the progress from outside
            Slider(value: $progress)
                .padding()
        }
    }
}
```

                progress: $progress
            )
            .frame(height: 60)

            Text("No Interpolation (Gaps)")
            WaveformScrubber(
                drawer: BarDrawer(upsampleStrategy: .none),
                url: shortAudioURL,
                progress: $progress
            )
            .frame(height: 60)
        }
        .padding()
    }

### Configure Waveform Upsampling Strategy

Source: https://github.com/lkora/waveformscrubber/blob/main/README.md

Control how the waveform is upsampled when the view is wider than the available samples. Options include smooth interpolation, hold interpolation, or no interpolation.

```swift
VStack {
    Text("Smooth Interpolation (Default)")
    WaveformScrubber(
        drawer: BarDrawer(upsampleStrategy: .smooth),
        url: shortAudioURL,
        progress: $progress
    )
    
    Text("Hold Interpolation (Blocky)")
    WaveformScrubber(
        drawer: BarDrawer(upsampleStrategy: .hold),
        url: shortAudioURL,
        progress: $progress
    )
    
    Text("No Interpolation (Gaps)")
    WaveformScrubber(
        drawer: BarDrawer(upsampleStrategy: .none),
        url: shortAudioURL,
        progress: $progress
    )
}
```

### Bezier Curve Waveform Rendering (SwiftUI)

Source: https://context7.com/lkora/waveformscrubber/llms.txt

Demonstrates the usage of the BezierCurveDrawer for WaveformScrubber to render smooth, organic waveform curves with adjustable curviness and pixels per sample. This SwiftUI snippet requires the WaveformScrubber library and configures a fluid visual representation of audio data.

```swift
import SwiftUI
import WaveformScrubber

struct BezierWaveformView: View {
    private let audioURL = Bundle.main.url(forResource: "audio", withExtension: "mp3")!
    @State private var progress: CGFloat = 0.3

    var body: some View {
        WaveformScrubber(
            drawer: BezierCurveDrawer(
                config: .init(
                    curviness: 0.8,
                    pixelsPerSample: 4
                )
            ),
            url: audioURL,
            progress: $progress
        )
        .frame(height: 100)
        .padding()
    }
}
```

### WaveformScrubber: Render as Stroke Outline with LineDrawer/BezierCurveDrawer (SwiftUI)

Source: https://context7.com/lkora/waveformscrubber/llms.txt

Demonstrates rendering a waveform as a stroked outline using either LineDrawer or BezierCurveDrawer. This approach is useful for emphasizing the waveform's shape without filling it. It requires SwiftUI and the WaveformScrubber library.

```swift
import SwiftUI
import WaveformScrubber

struct StrokeStyleView: View {
    private let audioURL = Bundle.main.url(forResource: "audio", withExtension: "mp3")!
    @State private var progress: CGFloat = 0.35

    var body: some View {
        VStack(spacing: 20) {
            Text("Stroke with LineDrawer")
            WaveformScrubber(
                drawer: LineDrawer(),
                url: audioURL,
                progress: $progress
            )
            .waveformScrubberStyle(
                StrokeWaveformScrubberStyle(
                    active: .orange,
                    inactive: .orange.opacity(0.3),
                    lineWidth: 2
                )
            )
            .frame(height: 80)

            Text("Stroke with BezierCurveDrawer")
            WaveformScrubber(
                drawer: BezierCurveDrawer(),
                url: audioURL,
                progress: $progress
            )
            .waveformScrubberStyle(
                StrokeWaveformScrubberStyle(
                    active: .green,
                    inactive: .green.opacity(0.3),
                    lineWidth: 3
                )
            )
            .frame(height: 80)
        }
        .padding()
    }
}
```

### Customizing WaveformScrubber with LineDrawer

Source: https://github.com/lkora/waveformscrubber/blob/main/README.md

Illustrates using the `LineDrawer` for WaveformScrubber to create a solid, filled line shape. The `inverted` configuration option is demonstrated, which can be used to create a "cutout" effect on the waveform.

```swift
WaveformScrubber(
    drawer: LineDrawer(config: .init(inverted: true)), // Create a "cutout" effect
    url: audioURL,
    progress: $progress
)
```

--------------------------------

### Style Waveform with Stroke

Source: https://github.com/lkora/waveformscrubber/blob/main/README.md

Apply a stroke outline to the waveform instead of a filled shape using `StrokeWaveformScrubberStyle`. This is particularly useful for drawers like `LineDrawer` or `BezierCurveDrawer`.

```swift
WaveformScrubber(drawer: LineDrawer(), url: audioURL, progress: $progress)
    .waveformScrubberStyle(
        StrokeWaveformScrubberStyle(style: .orange, lineWidth: 2)
    )
```

--------------------------------

### Customizing WaveformScrubber with BezierCurveDrawer

Source: https://github.com/lkora/waveformscrubber/blob/main/README.md

Presents the use of `BezierCurveDrawer` for WaveformScrubber to render a smooth, organic waveform shape. Configuration options like `curviness` and `pixelsPerSample` are available to fine-tune the curve's appearance.

```swift
WaveformScrubber(
    drawer: BezierCurveDrawer(config: .init(curviness: 0.8, pixelsPerSample: 4)),
    url: audioURL,
    progress: $progress
)
```

--------------------------------

### Style Waveform with Solid Colors

Source: https://github.com/lkora/waveformscrubber/blob/main/README.md

Apply solid colors to the active and inactive parts of the waveform using the `.waveformScrubberStyle()` modifier with `DefaultWaveformScrubberStyle`.

```swift
WaveformScrubber(drawer: BarDrawer(), url: audioURL, progress: $progress)
    .waveformScrubberStyle(
        DefaultWaveformScrubberStyle(
            active: .purple,
            inactive: .purple.opacity(0.3)
        )
    )
```

--------------------------------

### Add WaveformScrubber Dependency in Package.swift

Source: https://github.com/lkora/waveformscrubber/blob/main/README.md
