libGDX Oboe Reimplementation of the Audio interface for libGDX framework using Oboe and FFmpeg, which allows music to flow without any delay or another unpleasant distortion. And if you ever asked yourself "Why is my libGDX app music is so broken ?", then you've come to the right place.

Quick, show me some code !

Here is how do one essentially "use" this library (code in Kotlin):

class AndroidLauncher : AndroidApplication() {
    // Magic happens here:
    override fun createAudio(context: Context, config: AndroidApplicationConfiguration): AndroidAudio =
            OboeAudio(context.assets)

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        // Create an app like always
        val config = AndroidApplicationConfiguration()
        initialize(SomeApp(), config)
    }
}

How does this works ?

Using Oboe library from Google, you can create high-performance audio streams which may plug in and tweak some features in runtime to boost speed even further. This streams are native, so there is no GC that will slow things down. For audio decoding, this library also provide native tools: libavformat and friends (FFmpeg) with MP3, OGG and WAV support only. Such audio decoder is blazing fast, so combining that with oboe streams, we get ourselves responsive and fast Audio implementation.

State of features

Here is a table of known goodies and problems for certain features per file format (decoder):

Progress:

OboeAudio class:

• [x] newSound method (With OboeSound);
• [x] newMusic method (With OboeMusic);
• [x] newAudioDevice method (With OboeAudioDevice);
• [ ] newAudioRecorder method.
