I use this app:

To find vibrating things. You can find the frequency and compare to rotational speed of each accessory on the serpentine belt with a little math. Take video at 240 fps and count frames.

Also the best way to find sound source is an FFT app.

This is the one I use:

I've found a few bad wheel bearings using this app.
Thanks Andrew!!!!
