Sobre este som
This is a short room tone recording, lasting just under five seconds, capturing the steady background noise of an empty indoor space with no speech or music. It feels still and unobtrusive, like the quiet that settles when a room is left alone, and it gives an edit a sense of place without drawing attention to itself.
