This is not exactly what you describe but it may meet your requirements:

http://plugin.org.uk/timemachine/

It's a GUI program, but the GUI is just one big button, which may or may
not have a keyboard binding.

The program has an auto-record feature based on the signal level. here's
the command line help:

Usage timemachine: [-h] [-i] [-c channels] [-n jack-name]
     [-t buffer-length] [-p file prefix] [-f format]
     [-a] [-b begin-threshold] [-e end-threshold] [-T end-time]
     [port-name ...]

     -h show this help
     -i interactive mode (console instead of X11) also enabled
         if DISPLAY is unset
     -c specify number of recording channels
     -n specify the JACK name timemachine will use
     -t specify the pre-recording buffer length
     -p specify the saved file prefix, may include path
     -s use safer characters in filename (windows compatibility)
     -f specify the saved file format
     -a enable automatic sound-triggered recording
     -b specify threshold above which automatic recording will begin
     -e specify threshold below which automatic recording will end
     -T specify silence length before automatic recording ends

HTH, Chris
