squelch(1)

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 suppressed if its energy level falls below a certain threshold 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 suppressed.
