VariableSpeedNativepublic class VariableSpeedNative extends Object | Provides all the native calls through to the underlying audio library.
You should not use this class directly. Prefer to use the {@link VariableSpeed}
class instead. |
| Methods Summary |
|---|
| static native int | getCurrentPosition()
| | static native int | getTotalDuration()
| | static void | initializeEngine(EngineParameters params)

params.getWindowDuration(), params.getWindowOverlapDuration(),
params.getMaxPlayBufferCount(), params.getInitialRate(),
params.getDecodeBufferInitialSize(), params.getDecodeBufferMaxSize(),
params.getStartPositionMillis(), params.getAudioStreamType());
