All Implemented Interfaces:

AudioSink
```
public final class OggFileAudioBufferSink
extends ForwardingAudioSink
```
A sink for audio buffers that writes output audio as .ogg files with a given path prefix. When new audio data is handled after flushing the audio packetizer, a counter is incremented and its value is appended to the output file name.
Note: if writing to external storage it's necessary to grant the WRITE_EXTERNAL_STORAGE permission.

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`flush()`	Flushes the sink, after which it is ready to receive buffers from a new playback position.
`boolean`	`handleBuffer(ByteBuffer buffer, long presentationTimeUs, int encodedAccessUnitCount)`	Attempts to process data from a `ByteBuffer`, starting from its current position and ending at its limit (exclusive).
`void`	`reset()`	Resets the sink, releasing any resources that it currently holds.

- Method Detail
  - flush
```
public void flush()
```
    Description copied from interface: AudioSink
    
    Flushes the sink, after which it is ready to receive buffers from a new playback position.
    The audio session may remain active until AudioSink.reset() is called.
    
    Specified by:
    
    flush in interface AudioSink
    
    Overrides:
    
    flush in class ForwardingAudioSink
  - reset
```
public void reset()
```
    Description copied from interface: AudioSink
    
    Resets the sink, releasing any resources that it currently holds.
    
    Specified by:
    
    reset in interface AudioSink
    
    Overrides:
    
    reset in class ForwardingAudioSink
  - handleBuffer
```
public boolean handleBuffer(ByteBuffer buffer,
                            long presentationTimeUs,
                            int encodedAccessUnitCount)
                     throws AudioSink.InitializationException,
                            AudioSink.WriteException
```
    Description copied from interface: AudioSink
    
    Attempts to process data from a ByteBuffer, starting from its current position and ending at its limit (exclusive). The position of the ByteBuffer is advanced by the number of bytes that were handled. AudioSink.Listener.onPositionDiscontinuity() will be called if presentationTimeUs is discontinuous with the last buffer handled since the last reset.
    Returns whether the data was handled in full. If the data was not handled in full then the same ByteBuffer must be provided to subsequent calls until it has been fully consumed, except in the case of an intervening call to AudioSink.flush() (or to AudioSink.configure(Format, int, int[]) that causes the sink to be flushed).
    
    Specified by:
    
    handleBuffer in interface AudioSink
    
    Overrides:
    
    handleBuffer in class ForwardingAudioSink
    
    Parameters:
    
    buffer - The buffer containing audio data.
    
    presentationTimeUs - The presentation timestamp of the buffer in microseconds.
    
    encodedAccessUnitCount - The number of encoded access units in the buffer, or 1 if the buffer contains PCM audio. This allows batching multiple encoded access units in one buffer.
    
    Returns:
    
    Whether the buffer was handled fully.
    
    Throws:
    
    AudioSink.InitializationException - If an error occurs initializing the sink.
    
    AudioSink.WriteException - If an error occurs writing the audio data.
