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.
