<H2><A NAME="problemsrandpauses"></A>Problems: random pauses in output</H2>
Random pauses in output, for example when you've received
sound for several minutes from a given connection, then lose
three or four seconds of sound, or just random brief
interruptions in the sound you hear are most probably due
to:
<p>
<ol>
<li>The network you're communicating over, whether a local
network in your office or the global Internet, is busy and
sound packets are being delayed by other traffic. Unlike a
file transfer which can proceed at any speed, intelligible
audio requires not only adequate bandwidth (data rate) but
consistent delivery time. The latter condition breaks down as
a network approaches saturation. The only solution (other than
connecting to a faster network) is to reschedule your
conversation for a time when the network is less heavily
loaded. You may be able to reduce the severity of the pauses
in the sound you hear by increasing the <A
HREF="commreceive.htm">jitter compensation</A> time, which
delays playback of a transmission to provide a margin for
delayed packet to arrive.
<P>
<li>Other tasks running in the background on your computer or
that of your interlocutor may be stealing CPU cycles that <i>Speak
Freely</i> needs in order to compress/decompress or encrypt/decrypt
sound in real time. Terminate the background tasks.
