<H2>NAME</H2><PRE>
squelch - apply squelch to an audio signal
</PRE>
<H2>SYNOPSIS</H2><PRE>
<B>squelch</B> <I>level</I>
</PRE>
<H2>DESCRIPTION</H2><PRE>
<B>squelch</B> reads audio data from stdin, applies a squelching
algorithm, and writes the squelched audio to stdout.
Squelching a signal means that the output signal is sup-
pressed if its energy level falls below a certain thresh-
old <I>level</I>. A properly adjusted squelch setting suppresses
background noise but not any of the interesting signal.
</PRE>
<H2>OPTIONS</H2><PRE>
level The audio level below which the signal will be sup-
pressed.
