There is arecord from the package media-sound/alsa-utils, there's ffmpeg and 
even cvlc if you want/prefer to use CLI tools, but as far as I know they will 
all require some scripting to control start/stop time if you're not doing it 
manually.  Will probably require transcoding into MP3 from raw PCM audio 
capture (e.g. from pcm_s16le).

You could always record over a longer duration and then chop the bits at the 
start/end you don't wish to retain.
