I'm looking for a recording program to record my university lectures. My only two requirements are that: 1. It does use too much CPU power (Audacity seems to eat away at my battery way too quickly) 2. It records in a relatively small file (Quicktime under Lion refuses to record in the MOV format it used under SL. In SL, an hour's worth of lecture was about 50MB. Now it's about 150MB). Is there anything like it? Paid or free it fine.
