| android.media.audiofx.Visualizer.OnDataCaptureListener |
The OnDataCaptureListener interface defines methods called by the Visualizer to periodically
update the audio visualization capture.
The client application can implement this interface and register the listener with the
setDataCaptureListener(OnDataCaptureListener, int, boolean, boolean) method.

Data in the fft buffer is valid only within the scope of the callback. Applications which needs access to the fft data after returning from the callback should make a copy of the data instead of holding a reference.
| visualizer | Visualizer object on which the listener is registered. |

| fft | array of bytes containing the frequency representation. |
| samplingRate | sampling rate of the audio visualized. |
