Just as there is software that records video from a webcam if
movement is detected, it's not unlikely that there is (or could
easily be) similar applications
for audio, where sound is recorded (and logged) when it exceeds some
preset threshold. I don't know of any such software, but some Google
searching might turn up something.

Sound Forge has a 'threshold' recording option. I would imagine most other
editors would too ...
