Enclosing class:

TeeAudioProcessor
```
public static final class TeeAudioProcessor.WavFileAudioBufferSink
extends Object
implements TeeAudioProcessor.AudioBufferSink
```
A sink for audio buffers that writes output audio as .wav files with a given path prefix. When new audio data is handled after flushing the audio processor, 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.
