I agree it is tough to say what this noise might be, I hate to speculate and get you worried when it might be a very minor little problem. If you take it in to Nissan they'll probably key in on the CVT trans as a possible culprit for the whining noise, if it is experiencing problems don't worry, they will replace the unit under warranty (either the whole CVT or possibly the valve body).
It doesn't sound like anything to panic about, but I would take it in to Nissan and let them diagnose this. I would say in this case don't take it to a non-Nissan shop because if there is an issue with the CVT you'll want a Nissan trained tech looking at it. Good luck and let us know what you find out, it might just help someone else with a similar problem!
