<h2><A NAME="hardsamplebits"></A>Sampling: 8 vs. 16 bit</h2>

<P>For the best sound quality, 16 bit sampling is desirable. 
<i>Speak Freely</i> translates 16 bit Pulse Code Modulation (PCM)
samples into an 8 bit logarithmic encoding known as mu-law (祃aw),
which effectively squeezes 13 bits of audio information into
each 8 bit byte.  If your sound hardware supports 16 bit
samples, that mode is automatically chosen.  If, for some
reason, you want to run in 8 bit mode (which sounds worse and
doesn't run any faster) you can do so by checking the
Options/Use 8-bit Audio menu item.</P>

<P>If your hardware supports only 8 bit samples, this menu item
is automatically checked and disabled, since you don't have the
option of using 16 bits.</P>
