New version of the headless audio player Gadulka adds extended playback controls for volume, position, playback rate and more

Playback controls

The initial release of Gadulka enabled a consumer to simply play an audio file. It was very much a "play and forget". With version 1.6.3, several methods have been added to allow a consumer to control the playback of the underlying player:

Make it possible to pause and resume playback
Get the current track position of the player
Seek to a specific track position
Get the duration of the currently playing item
Get or set the volume of the player
Set the playback rate of the player (e.g. 1x, 2x, etc)

Updated docs and example

In this release, Gadulka adopts Kotlin's default documentation engine called Dokka. As a result, an online version of the docs can now be browsed at https://gadulka.iamkonstantin.eu

I also took the liberty of publishing an example of using the library, based on Gadulka's WASM target support. The demo app is available at https://gadulka.iamkonstantin.eu/wasm/ and the source can be found in the repository.

Using Gadulka remains straightforward, and you can progressively adopt features as they become needed. Several convenience functions have been included in this release, so adopting Gadulka in Jetpack Compose and Compose Multiplatform is easier. There is no need for dependency injection or to manually set up the Android context.

@Composable
fun AudioPlayer() {
    val player = rememberGadulkaState()
    Row {
        Button(
            onClick = {
                player.play(
                    "https://download.samplelib.com/wav/sample-12s.wav"
                )
            }) {
            Text("Play")
        }
        Button(
            onClick = {
                player.stop()
            }) {
            Text("Stop")
        }
    }
}
