Reply to how to determine Project Rate in Audacity when recording from DJM-900NXS?

I know this is a simple question, but I've noticed that in Audacity, the Project Rate (Hz) option in the bottom left, defaults to a setting of "44100".. I noticed that Audacity records alright with a wide variety of Project Rate's, but from what I understand is that it has to match the Project Rate on your CDJ's + DJM.. I just want to ensure that I'm getting the best possible quality sound from my recordings..

currently using:

2x CDJ-2000 Nexus
1x DJM-900 Nexus
Audacity via USB

I read somewhere in the manual that it said 96000Hz, but i'm not sure if this was referring to Project Rate or what.. can anyone help clarify? Thank you!
