There's this.

It works on raw little-endian 16-bit PCM, though, not WAV. You'd
have to use sox to convert back and forth and pass auxtract the -c
and -s options so it knows the sample rate and number of channels.
If you need the gate the open and close gradually or some time
before/after the level goes above/below the threshold, this is not
it.
