# Directs audio input (e.g. mic) to audio output (e.g. speakers),
# then sleeps forever. Stops audio redirection when it is killed.
# So, for example, plug your phone into the PC's mic, run 'listen',
# and listen to phone audio through your computer's speakers.

# Requires:
# sudo apt-get install pactl
