Free simple tool for recording audio directly on disk - Recommendations needed

[Mark0]

I'm searching a simple application that could, potentially, be used to record hours of audio, directly in MP3 or OGG format.
Bonus points for something that could record in a loop, i.e. keep always the last xx hours, or minutes, etc.
Nothing really needed aside from that; will use some other software to edit the "raw" audio after that.

Thanks!

VU Recorder  (from the author of VU Player) is about as simple as it gets.
