### Remarks

Letting the internal buffer overflow will emit the [AudioSampleProvider.sampleFramesOverflow](/engine/6000.5/script-reference/unityengine/experimental/audio/audiosampleprovider/sampleframesoverflow.md) event and invoke the associated native handler set with [AudioSampleProvider.SetSampleFramesOverflowNativeHandler](/engine/6000.5/script-reference/unityengine/experimental/audio/audiosampleprovider/setsampleframesoverflownativehandler.md).
