I don't have rec or any hardware to do with sound, so I'll use "yes"
to demonstrate a program that runs until interrupted.  Not I use SIGHUP
rather than SIGINT, as bash provides a handler for SIGINT for background
jobs.  stdout and stderr don't have to be null, but they have to be
directed away from the terminal.

#!/bin/sh
yes >/dev/null 2>/dev/null &
sleep 1
kill -HUP $!
