Help!! I just started playing today and I'm on the part of the Peragus level where you need the Maintenence Officers voice to open the airlock. I'm stuck here. I tried to use the sonic thingy to record his voice but I can't seem to use it on the console to unlock the airlock. What do I do??

Never mind I figured it out.

Something I learned on my second playthrough -- you don't need the sonic imprint sensor at ALL to open the airlock. All you have to do is go to the terminal with high enough computer skills and simply "overload" the terminal to unlock the airlock.
