Whine noise from 2011 Honda CRV lx - occurs at medium RPM (starting at about 2500rpm). To me sounds similar to whine of an "electric" toy RC car/train.
Update: just got it checked out by a mechanic: apparently it's the bearing inside the transmission in the torque converter area. He told me that it's nothing to worry about, the sound probably shouldn't get worse, and that he's seen cars with this problem go 300k+ miles.
