Is the car moving with your foot on the brake when it makes this sound?

Calipers are what hold your pads and cause them to contact the rotors on your wheels when you brake with disc breaks. Basically, the calipers close up and cause your pads to contact your rotors.

i dont know about the "Caliper problem" it sounds like you have a transmission problem. some noise is to be expected when you shift out of park. it will sound like a 'clunk'. what kind of car, year, how long have you had it, ect.

Is the car moving with your foot on the brake when it makes this sound?

Yes, the car is moving while my foot is on the brake when it makes this sound.
