I used audio software to extract the voices of the children and of CBP officers from the recording. Despite containing none of the prominent voices heard in the original, the extracted audio featured the haunting reverberations of crying children and the background sounds of the detention center. This helped to illustrate the concept of “din” or the unwanted background noise of the border and the silencing taking place within the asylum system.
