What is the unit of sound when measuring by an Android smartphone?
<p>Here is my code</p>

<pre><code>    private static int Fs = 44100; 
    private byte recorderAudiobuffer[] = new byte [1024];
    AudioRecord recorder = new  AudioRecord(AudioSource.MIC, Fs, AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT, 4096);
    //start recorder
    recorder.startRecording();
</code></pre>

<p>A value is identified by bin[n] and bin[n+1] of recorderAudiobuffer[].</p>

<p>What unit are these values?</p>
