CLI Recording

[Daniel Hazelbaker]

I need a way to record from the CLI to an .aif (or .wav) from a  
specific audio device.  Reason being is we do timed recordings that  
we use as backups if our sound person forgets to hit record on the CD  
or there is a problem etc.  We do not want to depend on user  
intervention to click record.  Right now I use Linux, ALSA and  
arecord from a cron job to do this, but I would like to move to a Mac  
Mini running OS X.  Does anybody know of any software that will let  
me record from a cron job even if a user is not logged in?
