While my man page doesn't even show it, an ffmpeg -formats does show
that both are available as output formats.

A google search says the pcm_s16le is Signed 16 bit Little Ended. The
-ar says its to be 44.1 khz sample rate, and the -ac 1 says its mono, or 
one
channel.

You might get better audio at -ar 48000 as much of the audio around
seems to be sampled at that slightly higher rate.
