NAME

       squelch - apply squelch to an audio signal

SYNOPSIS

       squelch level

DESCRIPTION

       squelch  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 level.  A properly adjusted squelch setting suppresses
       background noise but not any of the interesting signal.

OPTIONS

       level  The audio level below which the signal will be sup-
              pressed.
