All Implemented Interfaces:

AudioProcessor
```
public final class TeeAudioProcessor
extends BaseAudioProcessor
```
Audio processor that outputs its input unmodified and also outputs its input to a given sink. This is intended to be used for diagnostics and debugging.
This audio processor can be inserted into the audio processor chain to access audio data before/after particular processing steps have been applied. For example, to get audio output after playback speed adjustment and silence skipping have been applied it is necessary to pass a custom DefaultAudioSink.AudioProcessorChain when creating the audio sink, and include this audio processor after all other audio processors.

public TeeAudioProcessor(TeeAudioProcessor.AudioBufferSink audioBufferSink)
```
    Creates a new tee audio processor, sending incoming data to the given TeeAudioProcessor.AudioBufferSink.
    
    Parameters:
    
    audioBufferSink - The audio buffer sink that will receive input queued to this audio processor.

  - onConfigure
```
public AudioProcessor.AudioFormat onConfigure(AudioProcessor.AudioFormat inputAudioFormat)
```
    Description copied from class: BaseAudioProcessor
    
    Called when the processor is configured for a new input format.
    
    Overrides:
    
    onConfigure in class BaseAudioProcessor
  - queueInput
```
public void queueInput(ByteBuffer inputBuffer)
```
    Description copied from interface: AudioProcessor
    
    Queues audio data between the position and limit of the input buffer for processing. buffer must be a direct byte buffer with native byte order. Its contents are treated as read-only. Its position will be advanced by the number of bytes consumed (which may be zero). The caller retains ownership of the provided buffer. Calling this method invalidates any previous buffer returned by AudioProcessor.getOutput().
    
    Parameters:
    
    inputBuffer - The input buffer to process.
  - onFlush
```
protected void onFlush()
```
    Description copied from class: BaseAudioProcessor
    
    Called when the processor is flushed, directly or as part of resetting.
    
    Overrides:
    
    onFlush in class BaseAudioProcessor
  - onQueueEndOfStream
```
protected void onQueueEndOfStream()
```
    Description copied from class: BaseAudioProcessor
    
    Called when the end-of-stream is queued to the processor.
    
    Overrides:
    
    onQueueEndOfStream in class BaseAudioProcessor
  - onReset
```
protected void onReset()
```
    Description copied from class: BaseAudioProcessor
    
    Called when the processor is reset.
    
    Overrides:
    
    onReset in class BaseAudioProcessor
