Sound Wave Pulse

Speaker card emitting a rhythmic sine-wave pulse drawn across the surface.

Ambient Mode

Installation

caveui components are copy-paste Jetpack Compose built entirely on Material 3 — there's no caveui dependency to add. Make sure Material 3 is on your classpath (it ships with the Compose BOM), then copy the Usage snippet below into your project.

kotlin

// build.gradle.kts (module)
dependencies {
    implementation(platform("androidx.compose:compose-bom:2025.06.00"))
    implementation("androidx.compose.material3:material3")
}

Usage

kotlin

@Composable
fun SoundWavePulse() {
  val t = rememberInfiniteTransition(label = "sw")
  val shift by t.animateFloat(
    initialValue = 0f,
    targetValue = (2 * PI).toFloat(),
    animationSpec = infiniteRepeatable(
      tween(1600, easing = LinearEasing),
    ),
    label = "shift",
  )
  Card(
    shape = RoundedCornerShape(20.dp),
    modifier = Modifier.fillMaxWidth(),
  ) {
    Column(Modifier.padding(16.dp)) {
      Row(verticalAlignment = Alignment.CenterVertically) {
        Icon(Icons.Default.Speaker, contentDescription = null)
        Spacer(Modifier.width(8.dp))
        Text("Ambient Mode",
          style = MaterialTheme.typography.titleSmall)
      }
      Spacer(Modifier.height(12.dp))
      Canvas(
        modifier = Modifier
          .fillMaxWidth()
          .height(48.dp),
      ) {
        val path = Path()
        val mid = size.height / 2
        path.moveTo(0f, mid)
        var x = 0f
        while (x <= size.width) {
          val y = mid + sin(x / 26f + shift) * 16f
          path.lineTo(x, y)
          x += 4f
        }
        drawPath(
          path,
          color = Color(0xFF34D399),
          style = Stroke(4f, cap = StrokeCap.Round),
        )
      }
    }
  }
