No, OOBE is for making the machine into a Like new Out Of Box Experience. Audit Mode is a tool to use during an Image setup process, that requires the finalization of the OS so it can (if you supply an unattend.xml) make your Installation autonomous.
The Audit mode is where you get to windows BEFORE the OOBE process happens. You are suppose to install all your software at this point then sysprep and upload, On first deploy the installation will answer the installation questions with your provided unattend.xml and complete the OOBE process (generalizing the installation so that new drivers can be applied to the system, cleaning some registry values and other secretive windows type things).
Really, there isn’t much difference in if you just install the software as a user and push your image, except the generalization processes which allows the machine that you are imaging to have their own hardware identifiers and unique strings which will be required for activation. This is only really important if you activate to a KMS server or if you join to an active directory environment (speculation have not tested I am not AD).
Try it, tell us what does and does not work if you don’t sysprep, that’s really the only thing I can recommend.
Personally, I read many tutorials before I began pushing windows 7. each one mentioned using Audit Mode to install my software and drivers before completing the generalization process, and I have had marginal success in doing so.
Hope this helps!
