Loud metallic squeal while driving

After driving for about ten minutes or so this loud metallic sound starts. The squealing sounds to me like it is coming from the right passengers side wheel. The loud metallic squeal occurs when driving and when lightly applying the brakes but stops when continuing to apply brake pressure in order to stop the vehicle. I have attached a sound clip of the noise it makes, this was recorded while driving without any brake pressure applied. I was wondering if this is a issue with the brakes (perhaps old hardware or worn pads) or something more serious.
