My sister had a similar sound coming from her Mazda, I immediately figured that it was the parking brake sticking slightly. It was making a dragging type of noise under certain circumstances. Even though it seems that my parking brake is way different from hers (my handle is way stiffer), it might be good to still check. My second theory was a wheel bearing going out on her car. FWIW I don't really know what it sounds like when a wheel bearing is going out lol.
If you think it is brake related- check the wheels for brake dust build up. What I mean by that- if one wheel obviously has way more brake dust buildup (especially inside the barrel of the wheel), I think you found your culprit.
Another way to check to see if your brakes are acting up, is to drive around a little, make sure to take it easy on the brakes. What I did was felt the differences in temperature of the two rear rotors with my hand, I'm not recommending that you use your hand for the possibility of the rotors burning you (obv). If the one of the sides of the brake is sticking then one side should be hotter than the other (or even the front rotors). It may have been a very specific case of one side sticking, but I ended up figuring it out.
