title: What is the byte format of an 8-bit monaural WAV file?
body: <p><strong>Setup</strong>:  WAV 8bit 8kHz mono PCM file.  </p>
  
  <p>By spec, 8-bit bytes are unsigned [0,255].  Is the byte value 2's compliment?  Is it simply binary offset?  <strong>What EXACTLY is the byte format?</strong>  </p>

Yet, <a href="https://www.dsprelated.com/showthread/comp.dsp/71057-1.php" rel="nofollow noreferrer">DSP discussions</a> say binary offset, meaning zero amplitude is 127?</p>
