Can you reccomend a screen capture application with audio? [closed]

I will soon be attending a web course.

Is there any application that can record the video and audio being outputted to my screen?

My goal is to record the class so I can watch it later.

Windows platforms preferred.


Camtasia is a great software for this, it is not free but there is a 30 day trial.

Camstudio is not as polished, but an open source, and free software to use.
