Recording Audio in CentOS

Today, I needed a tool to quickly and effectively record audio from a microphone connected to my computer, in order to test it.  I didn't have time to start playing around with Audacity settings to figure out how to get it to work properly, so I decided to look around for something else.  As it turns out, there is a nice little command line tool which allows for quick and dirty recording: sox.

All I had to do was:

$ sox -t alsa default out.wav

Bingo, instant recording for very basic purposes.  I'm sure the manual page will yield much more interesting features.
