Are ferrites effective for cabling?

Good day.  I have several ferrites in varying sizes.  Are they effective for eliminating noise or stray inductance/capacitance?  If so, would they be best utilized on interconnects or speaker cables, or both?  Or, should they not be used at all?  TIA for your thoughts.
Exactly! And it seems like such a good idea, too. File it along with other things that don’t work, like lead, Sonex, ERS cloth and keep moving. A rolling pebble gathers no moss.
