High pitch squealing sound in idle and very low speed

I hear a high pitch squeal when the car is idling or moving slowly through drive-through. The pitch/tone/frequency changes when I move from neutral to drive.
The noise goes away when I'm moving 10 MPH or higher or when revving the engine. My drive belts are tight, moderately used, do not have any cracks on them and visually look good.
The noise is loud but intermittent. I know Nissan has the official guidelines to check belt noise. Since this is intermittent, I'm having a hard time re-creating the noise on demand. Any suggestions?
